Product Description

The PS276-1 Powerpart 20 Amp Power Unit Transformer manufactured by BCA is a mains battery charger power unit/ transformer as fitted in some of the Bailey, Eldiss and Coachman ranges. It's primary function is to charge and recharge a battery as efficiently as possible. To ensure that battery charging does not occur, the PS276-1 has a fixed output voltage, and when connected to a mains supply the PS276-1 will raise the battery terminal voltage to it's fixed voltage output and therefore recharge the battery. A fan is fitted to assist cooling of the unit and will become operational when approximately 5A - 8A are being drawn from the unit. The fan switches off a low loads to ensure silent night operation. Complete with input and output via leads. The PS167 unit is a switch mode battery charger that can also be used as a standalone power supply.
