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.

With this voltage stabilizer, we recommend installing our LOSS OF NEUTRAL PROTECTION SUNTEK development. This device protects your equipment from burning out if the voltage on the neural wire is lost. Overvoltage occurs mainly due to breakage of neutral conductors, when the supply voltage is distributed unevenly between consumers or due to errors of personnel serving the electrical network. An open conductor breaks or burns out when the electrical network is overloaded (the load on the network increases every year); under adverse weather conditions, when food is produced by an air line (wind, fallen tree); during short circuits in the electrical network; with poor contact at the junction of neutral conductors; when stealing non-ferrous metal (wire); with old wiring in the home network.

We recommend installing LOSS OF NEUTRAL PROTECTION SUNTEK in front of a voltage stabilizer, for example SUNTEK. At high voltages in excess of 285 volts, the voltage regulator disconnects the entire load from the power source, but remains itself at high voltage, waiting for a lower line voltage. To protect not only your house from burning, but also a voltage stabilizer, install such protection in front of a voltage stabilizer, and you will receive complete protection against any voltage fluctuations in the network. The stabilizer and LOSS OF NEUTRAL PROTECTION SUNTEK are synchronized at the same voltage, for example, for SUNTEK voltage regulators, this is 285 Volts, in this case it does not reduce the operating range of the stabilizer, LOSS OF NEUTRAL PROTECTION SUNTEK, but serves as its additional protection and protection against burning out the neutral conductor which has often become commonplace in cities and villages.
