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.

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.
