The UPS consists of a charger, inverter and batteries to provide
regulated uninterruptible electrical power supply. When the static UPS
is in service, power from the primary AC source is supplied to the
charger unit. The charger converts incoming AC power to DC power to be
fed directly to the inverter unit. The inverter converts the DC power
into AC power to supply the critical load. Upon failure of the primary
AC supply, input power for the inverter is automatically supplied from
the battery bank with no interruption or disturbance of inverter
outputs. At the same time, the UPS alarms the loss of mains power
supply. When the AC power is restored, input power for the inverter unit
and for recharging the battery bank is automatically supplied from the
charger output, without interruption or disturbance.
