The Powerpart 20Amp Power Unit Transformer dual output with three stage charger PS306 with its advanced features and high level of reliability, make it one of the best units available. This unit is an electronic power unit that has been specifically for use within a caravan or motorhome. Its primary function is to supply power to operate the caravan or motorhome 12v equipment with the capability to charge and recharge a 12v auxillary battery as efficiently as possible. This model features a seperate Microprocessor Controlled Battery Charger Output.
Comes complete with full fitting instructions and fully guaranteed.
PS306-6A-BC is the new part number for the latest models and replaces all old units.
3 Stage Charging
BOOST - At switch on the charger is in boost phase where the charger output delivers 6 amps constant current until o/p voltage reaches 14.2v. At this level the charger enters Equalisation phase.
EQUALISATION - Charger output remains at 14.2v (constant voltage) for 4 hours. After 4 hours the charger enters Flaot phase.
FLOAT - Charger output switches to 13.8v (constant voltage) for 20 hours.
Note: Cherger performs Equalisation and Float every 24 hours unless the battery voltage falls below 14.2v in Equalisation mode in which case Boost mode will restart.
BATTERY DRAIN - When the mains is turned OFF this unit has a very low battery drain, the fiqure being only 0.0025 of an amp.
FAN OPERATION - To ensure silent night time operation the fan switches off at low loads. The fan will start to operate once the load current is in the region of 5amp - 8amp.
