Power Train DC To DC 30 Amp 12V Charger

Battery Charger DC to DC Battery Charging – Ideal for caravans, motorhomes, boats or anywhere dual battery 12 volt to 12 volt charging is required.

A DC to DC 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, since both batteries are now connected the vehicle attempts to charge both batteries from the vehicles charging system. When the vehicle is turned off the auxiliary battery is disconnected from the main battery so the auxiliary circuits do not drain the main battery, and enough charge is left in the main battery to restart the vehicle.

Features

• Model: PTCD12V30A

• 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 and won’t change unless you change the chemistry again.

• 3 Stage smart charging which comprises of BOOST, ABSORPTION and FLOAT ensures that Optimal charging is achieved using safe charging algorithms guaranteeing longer battery life and more usable power.

• The units micro-processor controller will protect against overcharging the auxiliary battery and ensures the main battery is not discharged below 12.4 volts. This will ensure the main battery is left with enough voltage to start the vehicle.

• 3 stage charge – bulk,absorption,float

• Battery type selectable: Gel/Calcium/Lead Acid-AGM

• Soft start

• Automatic equilisation
