3.2 Battery Mode
If the input AC power fails or the voltage drops below an acceptable level, the UPS
operates in backup mode. In backup mode the load continues to receive power from
the inverters, but the DC input to the inverter is taken from the batteries, instead of
from the rectifier.
The batteries are galvanically connected by DC link to the inverter and the charger.
The DC inherently remains constant when the AC input supply drops out, without any
switching devices.
The duration of the battery operation is determined by the load demand and battery
capacity.
