The automatic voltage regulator of SVEN AVR LCD series is designed to correct on-line power supply in conditions of stably low or high voltages. The wide range of input voltages from 100 V to 280 V allows operating the device in conditions of critical power supply state. The automatic voltage regulator is equipped with protection against short circuit, overload, overheating, overvoltage and under voltage.

The Pause function (6 or 180 seconds – at option) allows safe connecting devices-consumers to the power supply network at the moment of power supply renewal. The device is equipped with digital indicators, which display the input and output voltages. Due to its strong metal shockproof housing the automatic voltage regulator can be also used in technical premises such as a garage, workshop and boiler house.
