Power conditioning

Protects connected loads from surges, spikes, lightning, and other power disturbances.

Temperature-compensated battery charging

Prolongs battery life by regulating the charge voltage according to battery temperature.

Automatic restart of loads after UPS shutdown

Automatically starts up the connected equipment upon the return of utility power.

Automatic self-test

Periodic battery self-test ensures early detection of a battery that needs to be replaced.

Cold-start capable

Provides temporary battery power when the utility power is out.

Disconnected battery notification
