5. APPLICATION

Automatic voltage regulator (AVR) is designed for providing various equipment with high-quality

stable electric power supply in conditions of signiﬁcant and continuous deviations of mains voltage

and protecting your equipment from high-frequency and high-voltage impulses.

6. INSTALLATION

Attention! Before connecting the regulator, make sure that all consumer devices con-

nected to it are off.

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

than AVR power. Taking into account the starting load and power factor of voltage consumers, it is

necessary to apply power margin factor of 1.2–1.5; for such equipment as air conditioners, fridges

and other electric motors it should be 1.5–2.

Attention! When choosing an AVR, it is necessary to know 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 below:

Note. When choosing or operating an AVR, it is always necessary to adhere strictly to such

dependence. If the condition stated above is not adhered to, warranty servicing becomes

void!

• Voltage consumers should be connected only if the AVR is oﬀ.

• Connect the AVR to a 220 V household mains (except for AVR-3000 model) and switch it on. Only

after this has been done, switch on voltage consumers connected to the AVR.

• If the AVR operates properly, a green LED (Normal voltage LED) lights up, the left digital display

shows input voltage of the AVR and the right digital display shows output voltage of the AVR.

• In case mains voltage goes beyond the permissible range (± 8 %), a red LED lights up.

Attention! If mains power supply drops, it is recommended that you switch off the AVR and

all voltage consumers and switch them back on only after power supply has been fully

restored.
