An optional battery charger card is available for connection with the power
supply. This card is mounted on the power supply voltage regulator using 3
supplied standoffs. It provides a third‐party 24 volt, lead‐acid battery with .4
amps of constant current.
Relays on the battery charger card detect voltages over 24 volts to deactivate
charging, while activating charging for voltages less than 24 volts.
