20 best voltage regulators
The household electrical network, as a rule, is far from perfect, and for this reason, there can be not only deviations from the standard voltage (220V) and the output signal shape (sinusoidal current), but also such phenomena as short circuit, overheating of wires, abrupt doubling phases (380V). Household appliances and electronic devices from such loads can simply burn out, and in such cases, compensation is rarely possible for anyone.
However, there is a way to prevent undesirable consequences - to install the stabilizer on the whole house (summer cottage) or on a separate device (gas boiler, refrigerator, TV, etc.). The review includes the best devices for protection and voltage equalization of different power and types: relay, electronic and electromechanical. The rating was compiled on the basis of the technical parameters of these devices, the opinions of specialists, and, of course, the owners, who, in their reviews, shared the available positive experience of operating one of the presented stabilizer models.
The best relay voltage stabilizers up to 1 kW
Low-power voltage stabilizers are most often purchased by owners of houses, apartments and computer repair shops. Due to frequent power surges and sudden power outages, gas boilers, computers, televisions, office equipment and other expensive equipment can fail. To avoid such problems, single-phase stabilizers up to 1 kW are bought.
5 BASTION Teplocom ST-555-I
The relay stabilizer BASTION Teplocom ST-555-I can reliably protect the gas boiler or refrigerator from interference in the power grid. It is designed for a fairly modest load - 400V * A, but this is quite enough to ensure the operation of electronic equipment in the country. He, of course, will not pull the whole house, but it will be able to protect equipment with highly sensitive microcircuits from unstable voltage in the network or short circuit. Convenient, wall-mountable or shelf-mountable, the stabilizer is small in size. Digital indication displays output parameters, for which the maximum possible deviation from 220V does not exceed 9%. The generated sinusoidal signal is free of noise and distortion, which creates favorable conditions for the operation of expensive equipment.
Owners who have been operating BASTION Teplocom ST-555-I for a long time note its reliability - the relay mechanism operates at a speed of up to 20 ms, not allowing overvoltage to the connected boiler. With general indicators of 145V, it manages to "pull" the norm from the network. If the safety threshold is exceeded, it immediately "cuts in" the cutoff, but this is better than letting the electronic circuits of the gas boiler burn out. Also in the reviews, users give many positive ratings to the stabilizer for its "vitality" and build quality. A vivid confirmation of this is the manufacturer's warranty, which lasts for 60 months.
4 Energy APC 1000
The equipment, judging by the reviews of the owners, perfectly fulfills its task - it equalizes the output voltage in the 220V network with the minimum possible error of 4%, which allows it to be used with household electrical equipment of any complexity. The most commonly used APC 1000 Energy is used to provide protection for modern gas boilers, the electronic systems of which are very sensitive to voltage surges. In addition, the device is reliable in operation, assembled using high quality parts, and will delight the owner with a long and impeccable service. The stabilizer has two output sockets for connecting devices, the total power of which should not exceed 1 kV * A.
Wall-mounted placement allows the device to be positioned in the most convenient and safe place.The relay system operates with a delay of up to 10 ms, completely eliminating the negative impact of network fluctuations on household appliances. Energy APC 1000 is perfect for use not only at home, but also in the country. The connected refrigerator, TV and other devices will be protected from short circuits, stray currents and interference arising in 220V networks.
3 Resanta ACH-1000/1-C
Undoubtedly, the most popular stabilizers today are the devices of the "Resanta" company. One of the best-selling models in the company's lineup is Resant's ACH-1000/1-Ts single-phase stabilizer. Third place in our ranking of the best! The device has an input voltage range of 140 to 260 volts and operates with an error of 8%. Equipped with overheating protection and anti-jamming protection. This is the most primitive 1 kW stabilizer, which is perfect for home use. It is a pity that Resanta has only 1 unit of stabilized output sockets. Competitors have an order of magnitude more of them (Powercom, for example, 4).
In the course of studying the reviews about "Resant ACH-1000/1-Ts", a lot of negative was found regarding the display of the average voltage value. Often the stabilizer shows 220 volts on the display, although when measuring the real output voltage, the value can be both 215 and 225 volts. An incompetent user will say that the device is openly “lying”. In fact, GOST allows a similar error. Plus, minus 5 volts (within 8%), this is nothing out of the ordinary. The development of Resant stabilizers belongs to Latvian engineers. Manufacturing is also carried out in Latvia, which favorably distinguishes Resant's products from many analogues produced at Chinese factories. At a minimum, the consumer gets a better assembly and a minimum of scrap.
2 Powercom TCA-2000
The second place in the rating is occupied by the Powercom TCA-2000 single-phase stabilizer. This is the lightest, most compact stabilizer in our TOP 3. The weight of the device is only 1.8 kg, and the dimensions are 12x10 cm. For such a stabilizer, there is a place everywhere, for example, under a computer desk. The device will look great next to a gas boiler. By the way, it is to ensure the reliable operation of gas boilers that such stabilizers are bought.
Powercom TCA-2000 is manufactured in Taiwan. The stabilizer is made according to the classic scheme: an autotransformer with relay-switched windings. In the Powercom rating, it has the best stabilization accuracy - the device error is only 5%. For two of his competitors, this figure is 8%. Another important “trump card” of Powercom TCA-2000 is the most affordable price. In 2016, this stabilizer could be bought for only 2,000 rubles.
1 Quattro Elementi Stabilia W-Slim 1000
An automatic voltage stabilizer will ensure the equalization of deviations in the household electrical network to a standard level of 220V and reliably protect equipment such as ventilation and air conditioning systems, gas boilers, pumping equipment (for a well) in the country or at home. It will also be useful to connect such expensive household appliances as a refrigerator through it - drops in the network will not be able to harm sensitive electronics.
In the reviews, the owners pay attention to the compactness of the relay stabilizer. Wall mounts allow you to place it in the most convenient place on the wall, which will save you from hanging wires (they can be placed in a special casing) and cases of careless use (when a gas boiler is in the kitchen, this possibility is most likely). The appearance of the model is also positively assessed - a compact rectangular case with digital indication will look organically in any room, and the power cord and load socket, located on one side wall of the stabilizer, make it possible to optimally solve the power cable routing by hiding them in a special box.
The best 10 kW relay voltage regulators
A distinctive feature of these powerful stabilizers is a relatively affordable price and the ability to provide adequate protection for household electrical equipment from network overloads. the category presents the best models of this type.
5 Wester STW-10000 NP
The Wester STW-10000 NP stabilizer is distinguished by the best response speed even to the most significant changes in the network. It is able to equalize the input voltage to the optimal value in less than 0.5 seconds, in the operating range from 140 to 260V. This device is permanently connected to the home network, since its parameters are quite enough to stabilize the voltage of the whole house, small office or summer cottage. Due to its high total power, Wester STW-10000 NP is able to protect any household and computer equipment from surges, with a total consumption of 10 kW.
This relay stabilizer has a high degree of protection - if the input voltage indicators exceed the permissible limits, the device will turn off completely until the situation normalizes. If the jumps turn out to be short-lived and insignificant, the stabilizer will continue to perform its task. Also, this device protects the home network from short circuits. The Wester STW-10000NP is controlled using toggle switches, and all the information necessary to monitor the situation is displayed on a digital display.
4 SUNTEK SNET-11000
This household network stabilizer is simply necessary in a country cottage or in a residential building. Several types of protection and voltage equalization to the norm of 220V, will protect electronic devices and expensive household appliances such as a refrigerator, washing machine or dishwasher, TV, air conditioner, etc. A feature of this relay stabilizer can be considered the presence of the Bypass system, which allows you to separate a protected branch in the home network so that the power of SUNTEK SNET-11000 with a margin is enough for expensive equipment.
In the reviews left, the owners positively assess the functionality of the device - it retains the 220V standard (+ -8%) in a secure network, while at the entrance to the device, the drop can reach 120V. This is especially effective when a neighbor in the country uses a welding transformer. Overvoltage above 285V leads to protection operation and disconnection from the network, since the relay mechanism can miss such surges. At the same time, a fairly high noise level of its work is noted. However, this factor does not have a serious impact on the choice of the future owner, since the affordable cost fully compensates for it.
3 RUCELF SRWII-12000-L
The third place in the rating of the best 10 kW stabilizers is taken by the RUCELF SRWII-12000-L device. The model has a slightly higher total power than the opponents - 12,000 VA. This will allow the device to be operated in networks with a slightly higher load (large household appliances, powerful electric motors). Its active power is standard for the top three - 10,000 watts.
The device stands out for the best efficiency among competitors - 98%. We also note the presence of a start-up delay, protection against short circuit, overheating and overvoltage. Only slightly overpriced paint thickens. RUCELF SRWII-12000-L costs about 25 - 40% more than stabilizers from the Resanta and Era brands. The development of RUCELF stabilizers belongs to Russian engineers, but the assembly is carried out in China.
2 Daewoo Power Products DW-TM12kVA
Relay stabilizer Daewoo Power Products DW-TM12kVA protects household equipment from overvoltage, overheating, network noise and short circuit. The response time to deviations from 220V is only 20 ms. At the same time, the switching of the relay is so quiet that the equipment can be located in the residential part of the house or summer cottage. The wall mount and the rather compact dimensions of the device (38.1x51.1 cm with a depth of 25.9 cm) will not take up much space even in a small hallway.
With a stabilization accuracy of 8%, this device reliably protects electronic devices by filtering network noise and interference. The correct sinusoidal current and even voltage are the basis for long and flawless operation of such expensive equipment as a gas boiler, refrigerator, washing machine or TV. The owners, who made a choice in favor of Daewoo Power Products DW-TM12kVA, were able to convince themselves during operation of the reliability of the South Korean stabilizer.Giving a positive assessment to this equipment in their reviews, users consider the more expensive cost of the device to be fully justified by its durability and quality of work.
1 Quattro Elementi Stabilia 12000
Another representative of the Quattro Elementi company, with high performance and deserved popularity among users. As in the case of the less powerful model, the Stabilia 12000 has the same key advantages - it is 98% efficiency, a wide range of operating mains voltage (140-270 V), the presence of three levels of protection and a start delay (attached to the possibility of connecting asynchronous devices).
However, these are not the only advantages of a high-power stabilizer (active power of which is 7.2 kW). With the growth of operational characteristics, there was a need for forced cooling of the device (which affects the increase in noise), equipping with a Bypass function for energy transit in the event of faults (or exceeding the humidity threshold), as well as replacing the sockets with more universal terminals. Among the shortcomings, there is still mediocre stabilization accuracy (about 8%), but with all the advantages and the level of cost, you involuntarily close your eyes to this. Moreover, the device shows excellent results in the general quality category.
The best electronic voltage stabilizers - ultra-precise devices
A little higher, we examined the rating of popular relay-type stabilizers. Electronic stabilizers with step regulation are considered more modern and expensive. The switching of turns in such devices is electronically regulated by thyristors and triacs. Due to this, the speed of processing disturbances increases, the stabilization error decreases and the noise of the device decreases. Electronic gimbals are great for home and office use.
5 Energotech NORMA 9000
The electronic stabilizer Energotech NORMA 9000 is disconnected from the network when the voltage drops to a critical level of 60V. Up to this limit, its transformer is able to ensure the operability of the device and generate an output voltage of 220V. In this case, the error does not exceed 7%. This performance was achieved through 9 stages of stabilization. The equipment will provide electricity to almost all household appliances - 9 kW of power will be enough for both a washing machine and an oven, not to mention a refrigerator, TV or gas boiler. Installation in a country cottage will deprive the owner of many problems, especially if the power grid to which the house is connected is in a worn-out condition.
The manufacturer, confident in the high quality of component parts and assembly, provides a warranty for a fairly decent period of 5 years. Thyristors work almost silently, and, judging by the reviews of the owners, in full accordance with the declared parameters. Energotech NORMA 9000 also provides protection against short circuits, overheating of the transformer winding, removes interference and stabilizes the output signal shape (sinusoidal current), which has a positive effect on the service life of household appliances and electronics. Also, many note the versatility of the ergonomic case, which can be wall-mounted.
4 Systems Ultra-M 9000
The Systems Ultra-M 9000 single-phase electronic thyristor-type stabilizer is able to equalize with an accuracy of 5% the input voltage in the 110-290V range, thanks to a 16-step stabilization system. Despite the minimum power consumption, this device is equipped with a unique transformer that has a triple power reserve. With the possible limit values of the input voltage from 60 to 300V, the stabilizer guarantees at the output 209-230V, which ensures reliable protection of all electrical appliances operating at home. At the same time, due to the presence of microprocessor control and thyristor switches, this device emits a minimum of noise.
The Systems Ultra-M 9000 Voltage Stabilizer has the longest lifespan, with a minimum of 10 years of continuous operation under maximum load conditions. This is facilitated by a robust metal case and multi-level protection against short circuits, impulse currents and overloads. This stabilizer will be the best solution to problems that may arise due to inconsistent voltage indicators in the country or in a country house. With it, you can not worry about the smooth operation of the refrigerator and gas boiler during the absence of the owner.
3 Energy Classic 7500
Energy Classic 7500 is an electronic regulator with a total power of 7500 VA. Third place in our ranking. It has the lowest disconnection threshold in the rating. This stabilizer is best suited for a house or apartment, where there is often a low voltage in the network. "Energy" turns off when the voltage drops to 60 V. In the TOP-3, this stabilizer has the best response time, that is, the device begins to compensate for the voltage drop faster than anyone else. The delay between a change in the input voltage and the beginning of its correction is only 20 ms. The efficiency of the device is 98%, which, again, is the best indicator in the trio under consideration.
Energy The Classic 7500 is a very light stabilizer for its power. The weight is only 20 kg. Thus, it can be wall-mounted, saving indoor space. According to the manufacturer, the Classic 7500 has a resource of 60,000 hours, or about 20 years of operation. From user reviews, it is worth noting such advantages of the stabilizer as excellent design and quiet operation.
2 Lider PS10000W-50
Lider PS10000W-50 is the most expensive device in our rating. The uniqueness of this stabilizer is that it can operate in a very wide input voltage range. Due to the booster transformer, the device can operate without loss of power with a minimum voltage of 128 V and a maximum voltage of 320 V. "Leader PS10000W-50" is a completely self-contained electronic device with a low noise level and does not require maintenance. It lacks a relay and a servo drive, which is most often worn out by single-phase stabilizers.
In the reviews of the owners who have chosen this voltage normalizer to protect the electrical network of their home, there are practically no complaints and complaints. Most often, many users indicate that after installing the stabilizer, they completely forgot about its existence and any anomalies - stable 220V reliably protect the refrigerator, gas boiler, TV and other equipment.
1 PROGRESS 8000TR
PROGRESS 8000TR is a modern, high-quality device from a Russian manufacturer. Number one in the ranking of the best electronic stabilizers. It is a highly efficient device with a full output of 8000 VA. Perfect for an apartment and a house, where overvoltage up to 305 V is often observed. In our rating, this stabilizer has the best stabilization speed equal to 500 V / s. It is known that the higher this indicator, the faster the device reacts to voltage changes.
It is impossible not to say about the best indicator in terms of stabilization accuracy. The PROGRESS 8000TR has a margin of error of only 3%. Among the shortcomings, according to user reviews, we note the excessive noise of the PROGRESS 8000TR stabilizer. Installation in a separate, non-residential area is recommended.
The best electromechanical voltage stabilizers up to 10 kW
Electromechanical stabilizers are, in fact, step-up transformers, with the advantages and disadvantages arising from their design. Despite the obsolescent design and the arrival of more advanced types on the market, they are still very popular and compete with mainstream electronic and relay models.The key feature of electromechanical stabilizers is that they independently regulate the voltage in the network, in contrast to the same relay competitors.
5 CALIBER ASN-10000/1
One of the budget electromechanical stabilizers is presented in the form of a floor structure. It has all the necessary degrees of network protection against critical loads, this device is capable of holding 220V at the output with an input voltage of only 140V. On the front panel there is a digital indication of operating parameters and toggle switches for bypass control and connection to a common network, as well as a packet fuse.
Despite the parameters that are quite decent for an electromechanical stabilizer, there is one quantity, the size of which, in many respects, determines such an affordable cost of protective equipment - this is the response time. In CALIBER ASN-10000/1, it is as much as 500 ms, which is simply a huge indicator in comparison with its closest competitors. Nevertheless, it is perfect for a summer cottage or a country house - a TV, refrigerator and even a gas boiler can be protected by this stabilizer.
4 Sturm! PS9315
The most optimal performance makes Sturm! PS9315 is a fairly popular stabilizer for installation in a country cottage or in a private house. Its advantage in the form of an affordable cost is almost undeniable. However, floor placement and the largest weight (57 kg) in the category make it impossible for the owner to compactly install the device in the hallway by hanging it on the wall. This stabilizer requires a separate place for itself, and it will not work simply to put it in the corner - the side walls are perforated for air access, and should not be limited by anything.
In terms of performance, the Sturm! PS9315 is pretty good. It maintains a stable 220V (+ -3%), even when the voltage drops to 140V at the house input. This certainly prolongs the life of the refrigerator, gas boiler and any other expensive equipment. The owners in their reviews point to a fairly serious protection from external factors. Thus, the stabilizer can operate in rooms with a humidity of up to 95% and an air temperature of at least -5 ° C, which makes it possible to install the device in an unheated dressing room at home (of course, only not in the northern regions of the country).
3 IEK Shift 10 kVA
A single-phase electromechanical stabilizer will fully protect all equipment in a private house or apartment. The possibility of wall placement and dimensions that are quite compact for such a power allow you to install IEK Shift 10 kVA without any problems even in a small hallway. Modern appearance, low noise level and high performance are considered the strong points of this model.
Maintaining a voltage of 220V at the output (the maximum possible deviation does not exceed 3%), the stabilizer will operate at 120V in the general network, which will save the owner from problems such as a burnt out refrigerator or gas boiler. The installation of the device in a country cottage looks especially relevant, where the power grid quite often works with abnormal drops. The owners who chose this device, in the reviews, indicate the full compliance of the declared characteristics with the real state of affairs. The stabilizer reliably protects equipment from voltage surges and short circuits. At peak surges, which it cannot cope with (more than 250V), the device simply cuts off the power supply until the network parameters are normalized.
2 RESANTA ACH-8000/1-EM
An interesting model of ACH-8000/1-EM voltage stabilizer from the Latvian company "Resanta" stopped just a step away from the leading position. The active power of this device is 8 kW, and the operating voltage range of the network varies from 140 to 260 V - optimal indicators for connecting a large number of small consumer electronics or high-power equipment within country houses (or medium-sized offices).The main advantage of this device lies in the stabilization error equal to 2% - relative to the leader of the rating, the gain is small (only 1.5%), however, for powering sensitive (delicate) equipment, such a spread can be very significant.
Also, the stabilizer has a Bypass mode, when turned on, it turns into a kind of passive element through which the transit of electricity with a network voltage indicator is carried out. RESANT ACH-8000/1-EM has no frankly weak sides - the stabilization device has three-level protection, high efficiency (97%), low cost and widespread in the domestic market ... only popularity among users is lacking.
1 RUCELF SDWII-12000-L
RUCELF SDWII-12000-L is one of the best stabilizers in its class, which is naturally confirmed by the leading position in our rating. According to users, the limit of applicability of this device is country or country houses, in which the voltage is often subjected to significant fluctuations. The stabilizer has excellent performance characteristics: an active power of 10 kW and a small stabilization error (only 3.5%) allow you to connect a significant amount of electronics to the device without fear of its safety. It is also important that the efficiency of the model is a brilliant 98% - in other words, the device operates practically without power losses.
The RUCELF SDWII-12000-L has four levels of active protection: short circuit, overheating, overvoltage and interference. If any malfunction is detected, the stabilizer can be switched to Bypass mode, which is, in fact, a transit mode, in which the device turns into a passive element of the network. Fortunately, such situations are extremely rare.
Voltage stabilizer for home - which one to choose?
Voltage parameters
The voltage stabilizer is selected for the type of network. Before buying, you should measure the voltage with a multimeter. If the voltage in the network is often reduced (90 - 140 V), you should choose devices that operate in the lower limits, from 90 V. And, conversely, with frequent overloads, they buy stabilizers with a high maximum input value, up to 270 V. This applies to single-phase stabilizers that stabilize voltage up to 220V.
Device power
An important rule of buying a stabilizer is that the indicator of its full and active power must be greater than the power of all network consumers (provided they are switched on simultaneously). The required active power of the stabilizer is determined as follows: the power of the network devices (computers, irons, televisions, multicooker, refrigerators) is summed up and added to the resulting value 20%. For devices with reactive loads, which at the moment of switching on have a power several times higher than the nominal (for example, a vacuum cleaner, an electric saw), one should be guided by the indicator of the full power of the stabilizer.
To stabilize the voltage of one room with a TV and a pair of computers, a 500 - 1000 V stabilizer is sufficient.
Efficiency
The efficiency indicates the efficiency of the device. The higher the efficiency, the better. You should focus on the purchase of stabilizers with an efficiency of at least 90%. Such devices are capable of consuming a little electricity under the greatest load.
Stabilization accuracy
The stabilization accuracy or error indicates the deviation of the output voltage value, which is indicated by the stabilizer. Measured as a percentage. The lower this indicator, the better.
You shouldn't buy devices with an error rate of more than 8%. Most budget models have an accuracy of 5-8%. This is enough to ensure reliable operation of the electrical network at home or summer cottage.
If the task is to ensure the stability of the network, in which devices demanding the quality of voltage are connected, such as pumps, refrigeration equipment, stoves and kettles, then they are guided by a stabilization error of no more than 5%.
