POWER SUPPLY OK
The AC input power is present.
The green "Load Protected" LED is on. The alphanumeric
display indicates the operating status of the UPS.
The power drawn by the load is supplied by AC input power
via the Rectifier and Inverter modules. The Battery Charger
float charges or recharges the battery.

The alphanumeric display reads:
LOAD PROTECTED
POWER SUPPLY OK
When AC input power fails or is out of tolerance, the Rectifier
shuts down and the battery supplies the power required by
the Inverter to supply the load. The battery discharges.
The green "Load Protected" LED is on. The alphanumeric
display indicates the operating status of the UPS.
The user is warned of operation on battery power by the
buzzer and by the yellow "Battery Status" LED. This
information is also available via the standard UPS
MANAGER DB15 connector.
During an AC input power failure, the duration of Inverter
operation on battery power depends on:
•
The rated capacity of the battery
•
The power drawn by the load
•
The battery temperature
•
The charge level of the battery
•
The age of the battery
The real backup time, which depends on the actual load,
may be greater if the Inverter operates at less than full rated
load. It is possible, during operation on battery power,
to increase the battery backup time by reducing the power
drawn by the load (shedding of non-priority load).
A low battery shutdown warning signal is available via the
standard UPS MANAGER DB15 connector for remote
