Abuse
protection
Reverse polarity
Charger self-protects without fuse clearing; indication via LED and
LCD; charger recovers automatically after removal of fault condition
Wrong voltage battery Charger-battery voltage mismatch shuts down charger after 5
minutes; indication via LED and LCD
Overvoltage shutdown Selective; shutdown only operates if charger causes the overvoltage
condition. Overvoltage caused by an external voltage source does not
shut down the charger.
Over temperature
protection
Gradual output power reduction if heatsink temperature becomes
excessive
