Battery Charger BT-BC 4 D

This microprocessor-controlled automatic battery charger is especially suitable for charging maintenance-free batteries as well as for maintenance charging and trickle charging of batteries which are not constantly in use.

Due to the integrated micro-processor, charging is done in three phases.

Phase 1 charges the battery up to about 85 % with an almost constant current.
Phase 2 charges up to 95% with constant voltage.
Phase 3 maintains the battery voltage at a constant level (IUoU curve) so that the battery is always fully charged.

An integrated diagnostic system shows faults and connection problems on the LED display.

The charging process is monitored and displayed.
