PC-25 Power/Standby UPS
The Alpha Communications® PC-25 (350VA) uninterruptable power
supply is primarily used with the NC300 / NC300II series and
HC345C series microprocessor based nurse/emergency call systems
and provides for uninterrupted power in the event of utility power
failures, voltage surges, spikes, brownouts and blackouts. It's
economical cost and extremely compact size will enhance the
operation of all your NC300, NC300II and HC345C systems.
When power is interrupted, the PC-25 immediately cuts in
to provide square wave power for the system's central
processing equipment until an emergency generator is activated or
power is restored. In the event of a prolonged power outage, the
PC-25 will provide power to the limit of its battery.
The green LED on the front panel indicates power line output when
steady and battery output when flashing. The unit also provides
an audible tone during battery output operation. Other features
include output receptacles for connection of equipment, power
cord for standard 120 volt, 15 amp power circuit, AC fuses to
protect the unit from utility power and DC fuses to protect the
battery. The PC-25 is U.L. Listed (#42T9).
