INTRODUCTION
The Model PS-30 is a regulated DC power supply design-
ed to match the KENWOOD TS-120S, TS-130S, TS-
130SE or TS-180S transceiver and provide reliable fixed-
station operation. External output terminals (5 A max.)
for operation of additional equipment are also provided.
CAUTIONS
1. The PS-30 will not operate if the output terminals
are shorted.
When the PS-30 power switch is turned on, make
sure that the transceiver's power switch is OFF; other
wise, current Greator than 2¢A may flow into the
transceiver if it is in transmit mode.
Or, the PS-30 may not operate if switched on with
the transceiver in transmit mode is turned on because
of the protection circuit.
Turn the transceiver's power on switch after the PS-
30 is turned on.
2. The fuses will blow if the unit is overloaded.
3. Allow sufficient space behind the unit and install in a
well-ventilated location.
4. Use the heaviest and shortest DC power cable pos-
sible from the Accessory Terminals.
If power cable length is excessive, the output voltage
will drop or induced RF energy may cause premature
protective shutdown of the PS-30.
5. When connecting two or more transceivers to the
unit or when using the supply for any other purpose,
check that the operating current is below the rated
current limit.
6. If the unit is checked without a load, approximately
16 V appears at the output. This is normal and is not
an indication of trouble.
INSTALLATION
Turn the Power Switch OFF before making connections.
Connect the AC power cord as shown in Fig. 2 or Fig. 3.
Note: When connecting the unit to the TS-120V or TS-
130V (10-W model), use the DC cable supplied
with the transceiver.
