Battery Charger DC to DC Charging and VSR In One Solution
Ideal for caravans, motorhomes, boats or anywhere dual battery 12 volt to 12 volt charging is required.
If you require 24 volt to 12 volt see our Redarc units
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 chemistry, etc.
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.
Three(3) stage smart charging:
The unit micro-processor controller will protect against overcharging the auxiliary battery and ensures the main batteries is not discharged below 12.4 volts.
