The PK250B Uninterruptable Power Supply provides
uninterrupted power in the event of utility power failures,
brownouts and blackouts. It is for use with the Tek-CARE®
NC300II Nurse Call System and the Tek-CARE®500 Wireless
Emergency Call System. Its economical cost and compact
size will enhance the operation of your system.
When power is interrupted, the PK250B immediately cuts in
to provide square wave power for the Tek-CARE® NC300II
Central Equipment or the Tek-CARE®500’s Tek-BRIDGE™
until an emergency generator is activated or power is
restored. In the event of a prolonged power outage, the
PK250B will provide power to the limit of its battery. The
green indicator 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, and power cord for standard 120 volt, 15
amp power circuit.
