Effective smoothing of impulse noise in the network 

An LCD display with a bluish tint gives the stabilizer an original and rather pretty look. Under the board there is a button to call the display on the board of the input voltage (to do this, click on it and hold, after you release the button, the output voltage value will reappear on the board). To the right of the board are LEDs that indicate the state of the output voltage - high, low, network.

SUNTEK servomotor voltage regulator will be your network status indicator from 120 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.

Warranty period of work 3 years, the term of operation not less than 20 years.


Loss of neutral protection

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.
