Inside the LCECCB board there is also a battery charger and protection against deep discharge. The battery charger takes power from the 230 VAC and the +24 VDC in the car and generates a constant voltage 13.65 V. The voltage can be adjusted. The current is limited to 450 mA. The board has two fuses:
