Automatic Voltage Regulator

5. INSTALLATION AND OPERATION GUIDE

Attention! Before connecting the regulator, make sure that all consuming devices connected

to it are off, and stabilizer switch is set to «OFF» position.

Attention! When choosing an AVR, it is necessary to consider that reduction of input

voltage increases value of input current, which means that maximum power of AVR is

reduced too! Such dependence is shown in the graph (Fig.5).

Note. Adhere strictly to such dependence. If the condition stated above is not adhered to,

warranty servicing becomes void!

• Before installing the AVR, please make sure that total power of all consumers is lower than AVR

power. Besides, take into account the starting load and power factor of consumers, it is

necessary to apply power margin factor of 1.2–1.5; it should be 1.5–2 for such equipment as air

conditioners, fridges, etc.

• Connect the necessary equipment to the power outlet (s) of the stabilizer.

• Connect the regulator to the power network of 230 V.

• Turn on the stabilizer. When the built-in LED lights up the key, and LED light up: for a short period

to test, «Стабилизатор» and «Перегрузка», constantly, «Сеть».

• When the self-test is complete LED «Перегрузка» will go out and voltage connection to the

output receptacles will happen. If the LED «Перегрузка» at the end of the test did not go out, it is

prohibited to operate the regulator to eliminate the problem.

• «Стабилизатор» LED will light when the regulator to increase or decrease in the input voltage.

• In case of overload or short circuit the thermal fuse is ready installed on the rear wall is trig-

gered. Turn on the stabilizer after removing the cause of the overload by pressing the power button.

• When voltage input is more than 280 V or below 150 V regulator will disconnect the load.

«Перегрузка» LED will light up.

• «Перегрузка» indicator will light up in case of overheating auto-transformer, protection will work.

The load deenergises. After cooling down auto-transformer load power is restored automatically.
