Single Line Diagram - Emergency Operation
Referring to Figure 3: In the event of an AC input source failure or interruption, the UPS
converter will de-energize and the UPS battery will immediately discharge and supply DC
power to the inverter to maintain continuous AC power to the load. This operation will continue
until:
a) The battery capacity expires and the inverter turns off, or
b) The input power is restored after which the converter will simultaneously power the inverter
and critical load and recharge the batteries.
A fully charged battery will provide power for the specified time at the rated load, or longer, at a
reduced load.
When power is restored after a low battery shutdown, the UPS converter automatically restarts
operation, the charger recharges the batteries and the Inverter is automatically restarted without
operator intervention. The load is automatically assumed by the inverter without operator
intervention.
