The RCE MOSFET electronic battery isolators are some electronic devices designed to direct the charging current to several batteries while preventing current from flowing from one battery to another.

The DC input power source may be an alternator, a charger, a wind turbine, a solar panel, a hydrogenator, etc.

The load distributors have a negligible voltage drop compared to conventional diode models which generate a drop of the order of 0.7VDC.

The RCE load distributors can be used with any type of generator including electronic models, thanks to its special IG (Ignition = priming) terminal.

The DC input power source will determine the rating of the splitter box:

For a 120A alternator, choose a 150A splitter (if a battery is either deeply discharged or short-circuited, the available input current may flow through the splitter box.)
