This is called an object model! The stabilizer can do a lot, install such a stabilizer on complex equipment and you will feel safe in the house! High speed response to changes in input voltage. Power surges are instantly “processed” by the microcircuit and relays (10 ms). Full nominal already when the input voltage reaches 140 volts. Automatic commissioning, continuous network testing. It is frost-resistant, temperature condition of work from -300 C to +500 C, compulsory cooling at high temperatures of a winding. Universal case - can be put on the legs, or hanged on the wall with a fastener (supplied with each stabilizer).
Short circuit protection
Overload protection (overheating)
Undervoltage protection
Overvoltage protection
Protection against impulse (lightning) discharges
Effective smoothing of impulse noise in the network

The board shows the output voltage of 220 volts . If, as a result of further voltage drop (and this is in the range of 120-140 Volts), the output voltage becomes less than the allowable then the board shows what kind of voltage comes out of the stabilizer. When the input voltage is less than 120 volts, the letter "L" lights up on the display, but for some time there is still voltage at the output of the stabilizer.
So the stabilizer will work even from 70 volts , but we must understand that its load level should then be less than the nominal. The stabilizer begins to perform its full characteristics from 120 volts. At a voltage in the range of 270-285 Volts, the actual output voltage will also be shown on the display. But when reaching 285-288 Volt, the stabilizer will immediately turn off by turning off all devices (the letter “H” on the display). The output voltage will be high and dangerous for the equipment.
The electronic unit of the voltage stabilizer SUNTEK is a fairly powerful microcontroller, in which the input and output voltage is analyzed and signals are generated to control the stabilizer keys. When forming the control voltage, the microcontroller takes into account the response time of keys and power relays. This allows for switching without breaks. As a result, the voltage waveform at the output of the relay stabilizer repeats the shape at the input.
SUNTEK voltage regulator will be your network status indicator from 70 to 285 volts . If you are interested, follow the state of the network, if you do not have time - the stabilizer will control everything himself and give the best option for this situation.

We use different color panel for relay type voltage stabilizers. Green color for CIS countries. Gray color is universal, we use for the rest of the world. There are no fundamental technical differences.
Warranty period of work 3 years, the term of operation not less than 20 years.
