The BARRETT 922 is a 13.8V DC regulated, 20 Amp power supply designed
to power the Barrett 500 or 900 series of HF transceivers and
accessories.

The 922 is designed to provide power for one 500 or 900 series
transceiver plus one accessory such as a modem. The 922 has a battery
standby system comprising a charging circuit with a true automatic
no-break changeover, in case of mains power supply failure. This
feature eliminates the problems of data modems re-setting during
mains failures and requiring re-initialisation. When mains is present
the power supply charges the battery at a maximum rate of 3 Amp. When
the battery is fully charged the rate is reduced to a trickle charge
to prevent over charging.

A fan option is available to allow 100% duty cycle operation when
operating HF data communication equipment. A convenient voltage
selector switch on the rear of the power supply enables quick
changing of the input voltage supply requirement to suit different
countries.
