DC POWER SUPPLY
KPS-12
OPERATING AND SERVICE MANUAL
The KPS-12 heavy-duty regulated power supply is designed for use with mobile transceivers operating as a fixed station.
It is not rated to supply power to more than one transceiver at a time. The KPS-12 may be used for other purposes if
INSTALLATION AND CONNECTIONS
1. The transceiver may be placed either on top or beside the supply.
2. Connect the KPS-12 to the transceiver with the DC power cable (Red +, Black —) supplied with the transceiver.
When installing the cable, the POWER switch should be OFF. If the DC power cable supplied with the transceiver
is permanently installed if your vehicle, another cable with connector, or connector only, may be ordered for
Operating with the KPS-12. (See Parts List on Page 2 and ordering information on Page 4.)
3. Adequate space should be provided between the KPS-12 heat sink and wall, curtain or any adjacent object for good
ventilation of both the KPS-12 and the transceiver.
4. The connecting cable between the power supply and transceiver should be as short as possible. If supply and
transceiver are not adjacent to each other, the connecting cable should be of heavy wire to minimize the voltage
drop. Also, a long connecting cable may act as an RF pick-up and cause spurious oscillation (RF feedback).
