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).
