A Line-Interactive UPS offers backup function and automatic voltage regulation (AVR). AVR regulates voltage to the appropriate level by decreasing it during surges or swells or increasing it during a sag or burnout. The advantage is better protection for sensitive IT and household equipment and avoids damage caused by a voltage up- and downturn.



AVR function also benefits the battery lifetime. As long as the voltage level is not lower than 70% to 90%, or higher than 110% to 125% AVR will adjust the voltage to a normal level. I case the voltage drops to a lower or higher level, the UPS will directly switch to battery mode to avoid dropouts and damage of the connected equipment.

Line-Interactive UPS offers USB port (RS-232) to connect to a multitude of operating systems for monitoring voltage, power and battery status.
