Charger terminology
1. Constant Current stage
- During this charge cycle, the batteries are charged at a constant current.
2. Constant Voltage stage
- During this charge cycle, the batteries are held at the constant voltage
(14.1V/battery aGM&Gel, 14.6v/battery FlooDeD) and accept whatever current (less than the
current in cc stage) is required to maintain this voltage. this ensures efficient charging.
3. Floating stage
- During this charge cycle, the batteries are held at the float voltage (13.5V/
battery).
If the a/c is reconnected, the charger will reset the cycle as above.
If the charge maintains at the float state for 21 days, the charger cycle will then reset.
Internal Circuit Breaker
the unit contains one 40a input circuit breaker located on the rear panel of the chassis adjacent to
the ac terminal block. the circuit breaker protects the charger circuit and bypass circuit. the circuit
breaker will trip on overload. reset the circuit breaker button after one minute duration.
Workshop sevicable Items
the PowerBack should only be opened for fuse inspection by an approved Sollatek repair workshop.
the fuse details are listed below:
