Caravan & Motorhome Battery Conditioner and Charger – 20Amp

SKU: PO123


BCA’s Power Unit Transformer Dual output c/w three Stage Power charger with separate 8A battery charger is the complete 12 volt supply unit, a fully automatic supply direct to the caravan and motorhome appliance and electronically controlled battery charging. Designed to operate in all European countries and charge a totally flat battery. All chargers will auto cut out on short circuit or overload.  To ensure a silent night time operation, the fan switches off at low loads. The fan will start to operate once the load current is in region of 5A – 8A

The easy to fit power unit comes with full fitting instructions and is fully guaranteed for one year from date of purchase.

There is now an extra white lead that is only used on 2015 Elddis and Bailey motorhomes – if you are replacing a transformer unit this lead can just be tucked out of the way and does not need to be connected to anything.
