Functional Description
The Low Voltage Disconnect assembly is a small PC board mounted on the
chassis plate of GE MDS packaged model radio systems. It prevents battery
damage that may be caused by allowing a backup battery to drop below 10.2
volts while powering a transce iver, such as might occur during a lengthy power
outage. Component locations are shown in
a schematic diagram.
When the battery voltage drops to 10.2 Volts (± 0.2V), the Low Voltage Dis-
connect Assembly automatically disconnects the battery from the transceiver.
This, of course, stops operation of the radio, but protects the battery from
potential damage. When AC power returns, the battery is automatically con-
nected to the power supply (for charging) and normal radio operation resumes
immediately.
