Top 20 voltage regulators

The household power grid is usually far from perfect, and for this reason it may not only have deviations from the standard voltage (220V) and the output signal form (current sine wave), but also such phenomena as short circuit, overheating of wires, abrupt doubling phase (380V). Household appliances and electronic devices from such loads can simply burn, and in rare cases it is rarely possible to get compensation in such cases.

However, there is a way to prevent undesirable consequences - to install a stabilizer on the whole house (cottage) or on a separate appliance (gas boiler, refrigerator, TV, etc.). The review is attended by the best devices for protection and equalization of voltage of different power and types: relay, electronic and electromechanical. The rating was made on the basis of the technical parameters of these devices, the opinions of specialists, and, of course, the owners, who, in their reviews, shared their positive experience in operating one of the stabilizer models presented.

The best relay voltage regulators with power up to 1 kW

Low-power voltage stabilizers are most often acquired by the 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 purchased. The average price of such a device is an average of 3000 rubles. Naturally, it is not such a large amount to show stinginess. After all, in the end, costs can be much more.

5 BASTION Teplocom ST-555-I

Reliably stabilizer BASTION Teplocom ST-555-I can reliably protect the gas boiler or refrigerator from interference in the electrical network. 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. Of course, he will not pull the whole house, but he will be able to protect equipment with highly sensitive microchips from unstable mains voltage or short circuit.Convenient, with the possibility of placement on the wall or on the shelf, the stabilizer is small in size. Digital indication displays output parameters, in which the maximum possible deviation from 220V does not exceed 9%. The generated sinusoidal signal is devoid of noise and distortion, which creates favorable conditions for the operation of expensive equipment.

Owners 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 passing an overvoltage to the connected boiler. With a total of 145V, he manages to "pull" the norm out of the network. If the safety threshold is exceeded, the cut-off is immediately “cut in”, but this is better than letting the electronic circuit of the gas boiler burn. Also in the reviews, users give a lot of positive ratings to the stabilizer for its “vitality” and build quality. A striking confirmation of this is the manufacturer’s warranty, which is 60 months.

4 Energy APC 1000

The equipment, judging by the reviews of the owners, perfectly performs its task - it aligns 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. Most often, the APC 1000 Energy is used to provide protection for modern gas boilers, whose electronic systems are very sensitive to voltage drops. 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 placement allows you to place the device in the most convenient and safe place. The relay system is triggered with a delay of up to 10 ms, completely eliminating the negative impact of network oscillations on household appliances. Energy APC 1000 is perfect for use not only at home but also in the country. A connected refrigerator, TV and other appliances will be protected from short circuits, stray currents and interference in 220V networks.

3 Resanta ACH-1000/1-Ts

Unconditionally, the most popular stabilizers for today are the devices of the Resanta company. One of the best-selling models in the company's line is Resant ACH-1000/1-Ts single-phase stabilizer. Third place in our ranking of the best! The device has an input voltage range from 140 to 260 volts and works with an error of 8%. Equipped with overheating protection and noise protection. This is the most primitive stabilizer with a power of 1 kW, which is perfect for home use. It is a pity that the output sockets with stabilization at Resanta are only 1 unit. The competitors have an order of magnitude more (Powercom, for example, 4).

In the course of studying reviews of “Resant ACH-1000/1-C”, 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 frankly "lying." In fact, GOST allows for a similar error. Plus, minus 5 volts (within 8%), this is nothing ordinary. The development of Resant stabilizers belongs to Latvian engineers. Production is also carried out in Latvia, which favorably distinguishes Resant products from a variety of analogues produced in Chinese factories. At a minimum, the consumer gets a better build and a minimum of marriage.

2 Powercom TCA-2000

The second place in the rating is taken by the Powercom TCA-2000 single-phase stabilizer. This is the easiest, most compact stabilizer in our TOP-3 best. The mass 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. Perfectly the device will look also near the gas boiler. By the way, it is to ensure the reliable operation of gas boilers such stabilizers are bought.

Production of Powercom TCA-2000 is carried out in Taiwan. The stabilizer is made according to the classical scheme: an autotransformer with relay-switched windings. In the Powercom rating it has the best indicator of stabilization accuracy - the error of the device is only 5%. Two of its competitors, this figure is 8%. Another major "trump card" Powercom TCA-2000 - the most affordable price. In 2016, this stabilizer could be bought for only 2000 rubles.

1 Quattro Elementi Stabilia W-Slim 1000

The automatic voltage regulator will equalize the 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 wells) in the country or at home. Connecting expensive household appliances, such as a refrigerator through it, will be useful as well, because drops in the network will not 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 eliminate the hanging wires (they can be placed in a special casing) and cases of careless use (when the gas boiler is in the kitchen, this possibility is most likely). The appearance of the model is also positively evaluated - a compact rectangular case with digital indication will organically look in any room, and the power cord and load socket located on one side wall of the stabilizer allow you to optimally solve the power cable routing by hiding them in a special box.

Top 10 kW Relay Voltage Stabilizers

A distinctive feature of these powerful stabilizers is a relatively affordable price and the ability to provide adequate protection for household electrical equipment against network overloads. The category presents the best models of this type.

5 Wester STW-10000 NP

Stabilizer Wester STW-10000 NP has a better reaction rate, even the most significant changes in the network. It is able to equalize the input voltage to the optimum value in less than 0.5 seconds, in the working range from 140 to 260V. This device is connected to the home network permanently, since its parameters are enough to stabilize the voltage of the whole house, small office or cottage. Due to the high rate of full 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 - in case the input voltage indicators exceed the permissible norms, the device will completely shut down 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 a short circuit. 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 stabilizer of the household network is simply necessary in a country cottage or in a residential building.Several types of protection and voltage leveling up to the norm in 220V, will protect electronic devices and expensive household appliances, such as a refrigerator, washing machine or dishwasher, TV, air conditioning, etc. A feature of this relay stabilizer can be considered the presence of a Bypass system, which allows a protected branch to be separated in the home network, so that the SUNTEK SNET-11000 has enough power for expensive equipment.

In the reviews, the owners positively assess the functionality of the device - it stores the standard 220V (+ -8%) in a protected network, while at the entrance to the device the drop can reach 120V. This is especially effective when a neighbor in the cottage uses a welding transformer. Overvoltage higher than 285V leads to protection and disconnection from the network, since the relay mechanism can skip such jumps. In this case, there is a rather high noise of his work. However, this factor does not have a serious influence on the choice of the future owner, since its affordable cost completely compensates for it.

3 RUCELF SRWII-12000-L

The third place in the ranking of the best stabilizers for 10 kW is taken by the RUCELF SRWII-12000-L device. The model has a little more full capacity than opponents - 12 000 V · A. This will allow to operate the device in networks with a slightly larger load (large household appliances, powerful electric motors). Its active power is standard for the top three - 10,000 watts.

The device stands out and the best efficiency among competitors - 98%. We also note the presence of a start-up delay, protection against short circuits, overheating and overvoltage. Thicken paint only slightly overpriced. RUCELF SRWII-12000-L costs about 25 - 40% more expensive than stabilizers from Resant 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

Daewoo Power Products DW-TM12kVA relay stabilizer protects household equipment from overvoltage, overheating, network noise and short circuit. The response time to deviations from 220V is only 20 ms. In this case, the switching of the relay is so quiet that the equipment can be located in the residential part of the house or cottage. Wall mounting and rather compact dimensions of the device (38.1x51.1 cm with a depth of 25.9 cm) will not take much space even in a small hallway.

With an accuracy of stabilization of 8%, this device reliably protects electronic devices by filtering noise and network interference. The correct sinusoidal current and even voltage serve as the basis for the long and flawless operation of such expensive equipment as a gas boiler, refrigerator, washing machine or television. The owners, who chose Daewoo Power Products DW-TM12kVA, were able to verify the reliability of the South Korean stabilizer during operation. Giving a positive assessment of 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 company Quattro Elementi, with its high performance and enjoying 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, an extensive range of operating mains voltage (140-270 V), the presence of three-level protection and start-up delay (attached to allow asynchronous connections).

However, these are not the only advantages of a high-power stabilizer (whose active power is 7.2 kW).With the growth of performance characteristics, there is a need for forced cooling of the device (which affects the increase in noise), equipping the Bypass function for energy transit in the event of malfunctions (or exceeding the humidity threshold), as well as replacing outlets with more universal terminals. Among the disadvantages is still the mediocre accuracy of stabilization (about 8%), however, with all the advantages and the level of cost, you involuntarily close your eyes. Moreover, the device shows excellent results in the category of general quality.

The best electronic voltage regulators - ultra-precise devices

Slightly above, we considered the rating of the popular relay type stabilizers. More modern and expensive are electronic stabilizers with step regulation. Switching turns in such devices is electronically regulated by thyristors and triacs. Due to this, the speed of disturbance processing increases, the stabilization error decreases, and the device noise level decreases. Electronic stabilizers are great for use at home and in the office.

5 Energotech NORMA 9000

The best electromechanical voltage stabilizers with power up to 10 kW

Electromechanical stabilizers are, in fact, step-up transformers, with advantages and disadvantages arising from their design. Despite the morally obsolete design and the arrival of more developed types on the market, they are still very popular and compete with electronic and relay models. A 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 budgetary electromechanical stabilizers is presented in the form of a floor construction. It has all the necessary degrees of protection of the network from critical loads, this device is capable of holding 220V at the output with an incoming voltage of just 140V.On the front panel there is a digital display of operating parameters and toggle switches for controlling the bypass and the connection to the common network, as well as with 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 the ASN-10000/1 CALIBER, it is as much as 500 ms, which is simply a huge indicator in comparison with its closest competitors. Nevertheless, it is perfect for giving or a country house - a TV, a refrigerator and even a gas boiler will be able to protect this stabilizer.

4 Sturm! PS9315

Best performance makes Sturm! PS9315 popular enough stabilizer for installation in a country cottage or in a private house. Its advantage in the form of affordable cost is almost indisputable. However, the floor placement and the largest weight (57 kg) in the category makes it impossible for the owner to compactly install the device in the hallway, hanging it on the wall. This stabilizer requires a separate place for itself, and it will not work just to put it in the corner - the side walls have perforations for air access and should not be limited to something.

As for performance, for its price Sturm! PS9315 is quite good. It maintains a stable 220V (+ -3%), even when the voltage at the entrance of the house drops to 140 V. This certainly prolongs the life of the refrigerator, gas boiler and any other expensive equipment. The owners in their reviews indicate a fairly serious protection from external factors. Thus, the stabilizer can work in rooms with a humidity of up to 95% and an air temperature of at least -5 ° C, which allows the device to be installed in an unheated dressing room at home (of course, not only 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 housing construction or apartment. The possibility of wall placement and dimensions that are compact enough for such power make it possible to install an IEK Shift 10 kVA even in a small hallway without any particular problems. Modern appearance, low noise and high performance are considered the strength of this model.

Supporting the output voltage of 220V (the maximum possible deviation does not exceed 3%), the stabilizer will operate at 120V in the common network, which will save the owner from such problems as a burned refrigerator or a gas boiler. Particularly relevant is the installation of the device in a country cottage, where the power grid often works with abnormal drops. Owners who choose this device, in a review indicate the full compliance of the stated characteristics of the actual state of affairs. The stabilizer reliably protects equipment from voltage surges and short circuits. With peak jumps that he cannot cope with (more than 250V), the device simply turns off the power supply until the network parameters are normalized.

2 RESANTA ACH-8000/1-EM

An interesting model of the ACH-8000/1-EM voltage stabilizer from the Latvian company Resanta stopped 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 - the 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 is the error of stabilization equal to 2% - relative to the leader of the rating, the gain is small (only 1.5%); however, for the supply of susceptible (delicate) equipment, this variation can be very significant.

The stabilizer also has a Bypass mode, when turned on, it turns into a kind of passive element through which electricity is transmitted with a network voltage indicator.Frankly, RESANTA ACH-8000/1-EM has no weak sides - the stabilization device has three levels of protection, high efficiency (97%), low cost and prevalence in the domestic market ... it lacks only popularity among users.

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 differences. 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. Also important is the fact that the model's efficiency is a brilliant 98% - in other words, the device works with virtually no power loss.

In RUCELF SDWII-12000-L, there are four active protection levels: short-circuit, overheat, over-voltage, and interference. In case of detection of any malfunction, the stabilizer can be transferred to the Bypass mode, which is essentially a transit mode, in which the device becomes a passive network element. Fortunately, such situations are extremely rare.

Voltage stabilizer for home - which one to choose?

Voltage parameters

Voltage stabilizer is selected for the type of network. Before buying, you should measure the voltage with a multimeter. If the mains voltage is often lower (90 - 140 V), you should choose devices operating in the lower limits, from 90 V. And, on the contrary, with frequent overloads, stabilizers with high maximum input value, up to 270 V, are bought. stabilizers that stabilize the voltage to 220V.

Device power

An important rule of buying a stabilizer is that its full and active power indicator should 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: sum up the power of the network devices (computers, irons, televisions, multicookers, refrigerators) and add 20% to the obtained value. For devices with reactive loads, which at the moment of switching on have a power several times higher than the nominal (for example, vacuum cleaner, electric saw), one should be guided by the indicator of the total power of the stabilizer.

To stabilize the voltage of one room with a TV and a pair of computers, a stabilizer with a power of 500-1000 V is sufficient.

Efficiency

Efficiency indicates the efficiency of the device. The higher the efficiency, the better. Focus on the purchase of stabilizers with an efficiency of at least 90%. Such devices are able to consume some electricity at the highest load.

Stabilization accuracy

The accuracy of the stabilization or error shows the deviation of the output voltage value, which shows the stabilizer. Measured in percent. The lower the number, the better.

Do not buy a device with an error of more than 8%. Most budget models have an accuracy of 5-8%. This is sufficient to ensure reliable operation of the power supply network at home or in the garden.

If the task is to ensure the stability of the network in which devices demanding of quality are connected, such as pumps, refrigeration equipment, stoves and kettles, they are guided by a stabilization error of no more than 5%.
