Daewoo Power Products DW-TM1kVA
In the first place is a relay stabilizer with a total power of 1000 VA, designed to operate in a single-phase network with a voltage of 220 V. The device is made in a compact white case 19x26x16 cm and is designed to be mounted on a wall. The user has access to two buttons on the side wall: the power key and the delay period setting. On the front side there is a digital display showing the input and output voltage data. Two sockets at the top allow you to connect a gas boiler and a water pump, if such a pump is “embedded” into the system separately. The input indicator can “float” from 140 to 270 V, but at the output the device will stably hold 202-238 V, so the gas boiler will be able to work correctly.
This model is great for the private sector, where there is a weak power line or where neighbors regularly use welding machines. Reviews show that the stabilizer works reliably when overheating or too large input values (“cuts off” the boiler) and aligns the network indicators well.
- can function from 140 V;
- digital display with two indicators;
- two sockets on the body;
- compact dimensions 19x26x16 cm.
- average response time at shutdown 20 ms;
- sometimes clicks loudly when triggered.
Powerman AVS 500S
The model is designed for a full power of 500 VA and can easily “pull” a boiler from 200 VA, even if the network drops to 170 V. The input current range is set by the manufacturer at 140-260 V. The stabilizer is installed on the wall using 4 dowels and cut holes for hanging. The ambient operating temperature is allowed from 0 to + 40 ° C, so it can be operated not necessarily in the living room, but even on the veranda or in the corridor. The device is made in a narrow metal case 17x29x7 cm and equipped with a small screen. To see the data, you need to switch “pages” with the button. The launch and delay buttons are located at the bottom.
The experts considered the stabilizer to be the best due to the reduced response time. The electronics are triggered in 5-7 ms, while the above model takes 20 ms. With such a stabilizer, your boiler and heating system will be better protected from sudden power surges.
- thin steel body;
- powder coating reliably protects metal from corrosion;
- built-in protection against interference and short circuit;
- digital display.
- only one socket;
- poorly thought-out natural cooling;
- the controls have to be looked for by touch.
The device measures 13.4x20x9.3 cm and is designed for wall mounting. The stabilizer is equipped with an active power of 600 VA, and the operating characteristics of the network are allowed in the range of 150-250 V. The alignment accuracy is at the level of 8%. In the reviews, buyers are pleased that this stabilizer is designed for short-term 130 V, at which it will not turn off, but will withstand some time. Thanks to this, the boiler and heating system will continue to work even in such extreme conditions. The manufacturer has provided three levels of protection: against too much voltage, short circuits and overheating. The estimated service life of the product is 10 years.
The stabilizer entered the TOP of the best due to the efficiency of 97%. This means that when stabilized, it loses voltage to a minimum (some competitors have an efficiency of 90%). The less losses, the more your gas boiler will get.
- optimal response time 10 ms;
- short-term input up to 130 V is allowed;
- there is overheating protection;
- perforation on both sides of the case.
- only one outlet;
- some don't like the build quality.
Powercom TCA-2000 (1 kW)
The device is available in a white or black plastic case with dimensions of 12x10x13.6 cm. The stabilizer is installed on the floor and emits a barely audible rumble with a volume of 40 dB. The active power of the device for protecting a gas boiler is 1 kW, the total power reaches 2000 VA, which makes it possible to supply gas heating appliances not only for small houses, but even for industrial workshops. Voltage stabilization is carried out in the range of 176-264 V. In the reviews, users are satisfied with the equalization accuracy of 5% (for competitors 8-10%), which provides 209 V at the output, instead of 198-202 V. But the stabilizer does not have a display, but only three diodes , showing in which direction there is a deviation in the network.
We put the product in the list of the best not only because of the increased power, but also because of the presence of 4 outlets. Thanks to this equipment, you can safely power a heating boiler, pump, boiler, and even a TV socket will remain.
- relatively affordable cost;
- perforation to improve natural cooling;
- two body color options;
- four sockets for connecting a boiler and other devices.
- no display;
- made of plastic;
- you cannot set the turn-on delay time;
- works correctly only starting from 176 V.
Energiya Voltron RSN-500 0.5 kVA
The relay-type stabilizer has 7 adjustment steps inside, which allows you to more accurately adjust the output voltage to the specified 220 V. The device's power is 500 VA. The front panel is equipped with a large two-row screen, where the incoming voltage is shown in red and outgoing voltage in orange. Users like this in their reviews, as it helps them navigate faster. A button under the display allows you to set the time delay after shutdown of 6 or 180 s. The response time for changing the mains reading is 10 ms, but the accuracy of the output current fluctuates within 10%.
The stabilizer is recognized as the best due to its extended operating voltage range. This model will continue to operate at 105 V when others have tripped. In this stabilizer, the automatics will “cut off” the gas heater only when the network sags to 95 V. Such a characteristic will help keep the boiler operating in case of sudden downward current surges, which will eliminate the need to restart the heating device. We recommend a stabilizer for the most “remote” summer cottages with a weak power line.
- large screen with color separation of indications;
- optimal response time 10 ms;
- continues to maintain boiler operation at 105 V;
- at overheating above 120 ° C, thermal protection is triggered.
- only one outlet;
- error up to 10%.
Teplocom ST-555-I 0.55 kVA
The relay model has four steps for switching the channels of the current passage to bring it to the level of 220-240 V. The operating range of the stabilizer is 165-260 V. But the stabilization accuracy here loses a little to some competitors and is 9%. The manufacturer has included a power of 400 VA in it. Plastic slim body can be hung on the wall or installed on the floor. The digital display with luminous numbers makes it easier to monitor the readings, but only one of the values is reported on the small screen at a time. The response time of the stabilizer is 20 ms. According to reviews, the device protects the boiler not only from current surges, but even from lightning strikes into the chimney, which has been repeatedly tested by users. In this case, only the fuse in the device burns out.
The stabilizer chip is a socket, which is not built into the case, but carried out on the wire, like a carrier. The plug does not stick out of the stabilizer, and the boiler is neatly connected further along the wire. If desired, the outgoing wires can be hidden altogether, which will further increase the aesthetics of the connection.
- improved natural ventilation of the case;
- digital display;
- universal placement;
- compact dimensions 13x17x8.5 cm.
- the cost is higher than that of others;
- response time 20 ms;
- accuracy 9%;
- plastic case.
Sven AVR SLIM-500 LCD 0.5 kVA / 400 W
The device for the safe connection of a gas boiler is endowed with a power of 500 VA and a stabilization accuracy of 10% in the range from 140 to 260 V. If there is a jump down or up, the stabilizer will respond to this within 10 ms, which is considered a good indicator among experts (like 4 to 5 point scale). The front panel is equipped with a digital display with alternating indication of input and output data, switched by a button. The socket for connecting the boiler is located on the side. According to reviews, the model perfectly and silently stabilizes the network that feeds the gas boiler.
According to its characteristics, the stabilizer is at an average quality level, fully justifying its cost. But we drew attention to it due to the thin case, which corresponds to the name Slim. The section of the block is 6 cm. This is one of the thinnest models that will take up less space in the allocated niche or will not stick out excessively from the wall. We consider the stabilizer to be an excellent option to secure the boiler's operation by placing protective equipment in the kitchen, where it will not attract too much attention.
- triggering in 10 ms;
- produces a sine wave without distortion;
- digital indication is provided;
- you can delay the launch.
- alignment accuracy at the level of 10%;
- only one socket for connecting the boiler.
RUCELF SRW-550-S 0.5 kVA
The review continues with a relay stabilizer from the domestic brand Rucelf, designed for boilers with a capacity of up to 500 VA. The device has one outlet on the side. There is also a power button. The front panel has three LED indicators that indicate the status of the electrical system. The operating range of the stabilizer is 170-260 V, and the correction accuracy reaches 8%, which in practice means an output with a voltage of 202-238 V. To prevent the device from overheating, perforations in the upper and lower walls are created in the case, and electronic thermal protection is also in effect. In the reviews, buyers praise the build quality and functionality of the device for a gas boiler.
We found the stabilizer to be the best in terms of value for money. For little money, you get a device with a good response speed of 10 ms and a package of protective functions (against too high and low voltage, against interference, in case of a short circuit, against excessive heating).
- thoughtful natural cooling;
- response in 10 ms;
- compact dimensions 22x15x7.5 cm;
- affordable cost.
- no display;
- only one 220 V output;
- the case is not protected from moisture.
IEK IVS24-1-00500 0.5 kVA
The gas boiler protection device is based on a new generation CPUII ++ microprocessor and provides increased stabilization accuracy. The model has dimensions of 20x17x12.5 cm and is designed for floor installation. The power button and the delay start button are placed on the side panel. Above there is one socket and a button for resuming the supply after a short circuit (fuse). The front side is equipped with a two-row display, the readings of which, according to reviews, are perfectly visible even in sunny weather. Relay regulator delivers 500 VA with 2.5 A alternating current
The stabilizer has two advantages at once. Firstly, it has a correction error of 6%, versus 8-10%, like most competitors. This allows for more accurate output data and makes the boiler easier to operate. Secondly, the voltage range without an emergency shutdown is 110-270 V here, so your gas heating will continue to function when other stabilizers have already cut off the power when the voltage drops below 130 V.
- Efficiency 95%;
- two-line display with bright glow;
- iron body;
- silent work.
- regulation time 20 ms;
- takes up space on the floor;
- high price.
Huter 400GS 0.4kVA / 350W
This model for a gas boiler is very similar in characteristics to the previous one: it provides a similar current range of 110-260 V, expanding the possibilities of maintaining the operation of gas heating. The stabilizer wins in terms of efficiency transmitted to the home network – 97% versus 95%. But it loses in terms of stabilization accuracy of 8%, when the above-described competitor has 6%. The device demonstrates the current parameters on a digital screen, but here it is single-row. To see each value, you need to switch the display with the button. Of the advantages – the presence of two outlets on the side wall, which allows, in addition to the boiler, to power one more device, which will be protected.
In our opinion, this is one of the best stabilizers in terms of response speed, which is 7 ms. (score 4+ on a five-point shackle). The microprocessor of the boiler will instantly be de-energized with an increased surge. With the current fluctuation of the current, the stabilizer will quickly adjust the output value to the optimal one.
- single row screen;
- two sockets;
- Efficiency 97%;
- range 110-260 V.
- not protected from moisture – cannot be hung in the bathroom;
- high price.
Shtil R 400T 0.4 kVA / 320 W
A device with six relay keys, allowing you to more accurately adjust the operating current for the operation of a gas boiler. The stabilizer has dimensions of 26x26x12 cm and is made in a solid metal case. The model is located on the floor vertically or horizontally. There is no display here, but the LED indication is extended. Six lit lamps inform the user about exceeding the maximum or minimum allowable voltage, correct operation of the network, overloads or erroneous phasing. Multiple perforations on the casing provide natural cooling and prolong the boiler's trouble-free operation.
Experts drew attention to the regulator due to one of the lowest voltage adjustment errors of 5.5%. Even with strong deviations in the network, the device will give out 208-232 V at the output, which will only benefit your gas boiler.
