OPERATING INSTRUCTIONS AND THEORY OF OPERATION
The model HB600W
®
and HB1000W
®
chargers are designed as semiautomatic chargers. The charger
turns itself on when it is plugged into the wall outlet and turns off when the batteries are fully charged.
Both the HB600W
®
and HB1000W
®
are two stage chargers. The first stage is a constant current mode. It
Maintains a constant current until the battery reaches a terminal voltage and then switches to the second
stage, constant voltage. At the second stage the charger decreases
the charger current while holding the batteries at the terminal voltage
until the charging cycle is complete.
The charger faceplate has three status LED’s that monitor the charging
status. Refer to the chart below.
