PowerTrain DC-DC 3 Stage Battery Charger 30A 12VDC

Smart battery charger

Ideal for caravans, motorhomes, boats or anywhere dual battery 12V to 12V charging is required. The PowerTrain DC-DC 3 Stage Battery Charger overcomes the problems associated with a VSR (voltage sensitive relay) or split charging systems that can struggle to charge correctly an auxiliary battery due to voltage drop or different battery chemistries, etc.

A VSR operates as a switching device that connects the auxiliary battery to the main vehicle battery when a specific voltage has been reached on the main battery. When both batteries are connected the vehicle attempts to charge both batteries from the vehicles charging system. When the vehicle is turned off the VSR disconnects the auxiliary battery from the main battery so the auxiliary circuits don’t drain from it.

The PowerTrain DC-DC 3 Stage Battery Charger offers the same VSR switching technology but adds a microprocessor controlled 3 Stage battery charger. This ensures your auxiliary battery can now be fully charged using the correct smart charging algorithm, overcome voltage drop due to long cable lengths, and still leave enough charge in the main battery to restart the vehicle.

PowerTrain DC-DC 3 Stage Battery Charger Features:

• A simple push of a button to set the charging profile to suit battery chemistry: GEL, calcium or lead acid/AGM. Once selected, the charger will store this in the memory
• 3 Stage smart charging - BOOST, ABSORPTION and FLOAT
• Microprocessor controller ensures the main battery is not discharged below 12.4 volts
