20A split charge relay for leisure/caravan batteries.
Charging automatically controlled by sensing vehicle battery/alternator voltage, meaning the vehicle battery charging is given priority, and leisure battery is disconnected when the vehicle engine stops.
This relay can either be used to charge a vehicle based leisure battery, or when wired to a standard 12S trailer socket will allow the vehicle to charge a caravan based leisure battery and power the refrigerator while the vehicle engine is running.
