When your vessel or yacht is equipped with two or more batteries, each serving distinct systems, Battery Isolators enable them to access a shared charging source while being discharged independently.

Frequently utilized to preserve the charge of the starting battery, Battery Isolators allow the simultaneous use of a secondary battery for various accessories (such as sound systems, refrigeration, emergency lights, computer equipment, etc.). This setup mitigates concerns about a depleted battery when initiating the engine.

CRISTEC RCE BATTERY ISOLATORS

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 RCE battery isolators have a negligible voltage drop compared to conventional diode models which generate a drop of the order of 0.7VDC.

They 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 battery isolator:

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

Specifications: CRISTEC RCE BATTERY ISOLATOR - 1 INPUT / 2 OUTPUTS - 150A
