Caravan Battery Charger

Can I use a MEAN WELL PB-300 Series Battery Charger in My Caravan?

The answer is not without the battery charger being modified first. 

Generally speaking, 12V batteries are used in caravans. If you are thinking of using the PB-300P-12 we recommend you consider using the PB-360P-12CDM instead.

The critical thing here is to ensure the part number of the battery charger you order has the ‘CDM’ suffix. This indicates that the charger has been modified so that it can be used in a caravan. 

If you cannot use the PB-360P-12CDM, Power Supplies Australia can modify the PB-300P-12. The cost is in the region of $120-$150 including GST.  

In many cases equipment in the caravan, such as refrigerators, can be running when the battery is being charged. This can cause the charger to over-charge the battery, which can shorten the battery’s life.  

The PB-360P-12CDM behaves differently to the standard PB-300P-12 and PB-360P-12 models and will not over charge the caravan’s batteries.
