The split charge module is the centre of the Powercentre system.
Providing a central  data collection point for the display module, housing the split charge relay / relays that provide the link for charging the service batteries from engine or mains battery charger, input for the interface to the mains battery charger, and output to drive a remote power-lockout relay.
There where two basic types, twin ( two battery banks ) and triple ( three battery banks ) split charge relays, both units were controlled by the display module.
Twin relay used with a single engine, with engine battery and service batteries, provides charge to the service battery from the engine, maintaining priority to charging the engine battery, before charging the service bank. A second function of the relay is to charge the engine battery when a Powercentre mains battery charger is fitted.
Triple relay used with twin engines / twin battery banks, and provides charging to a third service battery bank from each engine, priority is maintained to the engine batteries. Additional functions include charging both the engine batteries when a Powercentre mains battery charger is fitted, if an alternator fails the system will rollover to charge the battery bank with the faulty alternator. Some boats had the drop out function activated, this would isolate the starting battery from the service bank, if engaged, to maintain a clean power supply.
PLEASE NOTE the split charge relays are controlled by the display electronics fitted to the switch panel situated in the cabin.

A modified triple relay included a shunt for the mains battery charger output amps, and auto power up for the charging distribution circuit when the charger was on. These were fitted to the Sealine 328 and 365 that had the additional bar-graph and digital voltmeter fitted.

In addition to the charge modules, we supplied a range of shore / generator AC mains selector relays. These would always use shore power when available, otherwise the on board generator would be selected.

Control relays were also supplied to controll charge to the generator battery on certain Sealine cruisers, plus other specialised functions. If you have a unit you are not sure of and cannot identify please supply us with a photograph, and we will attempt to identify the unit.

Please use the following to identify your  Powercentre split charge relay, or control relay, then click on spare relays page to check price and order on line.

 

note

relays may be black or white plastic, colour has no effect on use or operation, if in doubt contact our technical office.
