3.2 Operation From AC Input
When the line power is normal, the static switch connects the line to the load
through an inverter which filters and regulates the power to the load. The
inverter also charges the battery.
It is also possible to operate the system without the use of the battery. In this
case, the unit provides excellent regulation and filtering of the incoming AC line
but without battery backup capability.

3.3 Operation From Battery
During the loss of commercial AC power, the battery provides DC current to
the inverter which then converts it to reliable, accurate AC power. A precision
frequency standard provides a highly stable frequency which is closely
regulated to the nominal output frequency.
In the event of a power interruption, the static switch disconnects the
commercial line from the inverter. The battery supplies power to the load via
the inverter.
