2-10 9390 Reference manual
Power supply
Ensure that the power supply and power cable for the
transceiver is suitable for correct and safe system operation.
For both 12V and 24V DC systems the power source can be
mains operated or battery.
Mains operated supply
We recommend the Codan AC power supply 9113 or 9114
for 12V DC operated 9390 front or extended control
transceivers. The 9114 is necessary if you are going to use
your transceiver for fax or data transmissions.
We recommend the heavy duty AC power supply accessory
code 507 for 24V DC operated systems using the 9390-H
receiver-exciter and the PA type 4404.
Battery supply
You can use standard, heavy duty 12V or 24V batteries as the
system supply. If a 12V system has to be powered from a
24V battery, install the accessory code 508 voltage regulator
(12V) within two metres of the transceiver.
DC power cable
It is important that the size of the DC power cable (cross
sectional area) is sufficient to keep the voltage drop between
power source and transceiver within close limits.
To check the effectiveness of the power cable installation
with the tuner and antenna connected, press the
Tune
button
and measure the voltage at the transceiver end of the cable.
The voltage should not drop more than 0.5V compared with
the voltage on receive only.
