Power Conditioning - Toshiba 1800 Series User Manual

Power conditioning

While commercial power is present, the UPS supplies conditioned power to the
load while maintaining the batteries in a charged condition. The UPS protects
the connected load against the normal everyday problems associated with
heavy use of raw commercial power, including power sags, signal interference,
and spikes. This protection keeps power-line problems from reaching your
load where it can cause equipment to operate erratically, or damage software
or hardware.
