  • Easy installation with high quality screw type wire connections
Our DCDC30A charger is a serious machine that can draw up to 50A from your vehicle's alternator. In order to protect your alternator we have included a feature that reduces the charging current progressively if the input voltage from the alternator drops and approaches 13V. It is therefore necessary to use wire sizes as specified to prevent charge current reduction as a result of voltage drops over supply wires.
