Dual Input: This Charger is designed to effectively pull power from solar panel (up to 40A) or vehicleÃ¢ÂÂs alternator to charge your auxiliary battery.
Multi-Stage Charging: This charger integrates standby, pre-charge, constant current charging, constant voltage charging, full charge and re-charge.
Multi Battery Selection: This DC to DC charger by ATEM POWER is compatible with Lead Acid, AGM, Gel, calcium, LiON batteries.
Built-In MPPT Regulator: The regulator is designed to harvest up more energy from the solar panel, thus reducing the load on your engine.
Multiple Protection: It integrates over-charge, short circuit, over-temperature, thermal load, solar input overload, input/output reverse polarity protection.
Internal Temperature Monitoring: This mechanism can effectively protect the circuit board, thus prolong the lifespan of the charger.
Sturdy Construction: Sturdy aluminum housing is built to resist harsh conditions and quality wires are built for long last durability.
Upgraded Charging Algorithm: This algorithm is designed to select the optimum charge mode and revive your discharged battery.
User Friendly Design: The LED indicator shows real-time stage of charging and memory function is integrated to make your charging more convenient.
Please note: always refer to the wiring diagram in this listing for the latest wiring setup of the product as the user manual might be for previous version.
