Qoltec Ladegerät DC-DC 12V mit MPPT-Regelung 40A

Compatible with many battery types

Our DC-DC charger is designed for seamless collaboration with a variety of battery types such as AGM, GEL, STD, Calcium, and LiFePO4. It allows for efficient charging of batteries from different sources without damaging them. With the convenient mode button, you can easily switch between charging modes, indicated by LEDs. Ideal for 4WD vehicles, caravans, trucks, and off-grid systems, it is also suitable for boats and yachts.

Stable voltage, safe operation, longer battery life

Connecting the battery to the Qoltec DC-DC 12V charger via an Anderson connector is done according to the cable colors and markings on the device housing. Anderson connectors facilitate a secure installation and removal, minimizing the risk of accidental disconnection or short circuits.

Full control of the charging cycle

The device automatically detects when to start and stop charging, ensuring convenience and safety: it begins charging as soon as a correctly connected battery and power source are detected, and it automatically stops the charging process when the battery is full, switching to float mode or completely disconnecting the charging current.

Intelligent 3-stage charging

The DC-DC charger charges your starter battery using an intelligent 3-stage process: The bulk phase identifies the battery and charges it up to 80% with constant current and high voltage. The boost phase, known as absorption charging, maintains the charging voltage while reducing the input current. The float phase is the final charging stage, where the charge reaches 100% and the voltage is kept constant.

Safety is a priority

The DC-DC chargers are equipped with comprehensive safety features, including protection against reverse polarity, short circuits, and overheating.
