DAMA WM686 4 Pin Split Charge Continuous Duty SPST Relay | Pack of 1
DAMA WM686 4 Pin Split Charge Continuous Duty SPST Relay is used for split charging or various automotive applications. "Split charging" is the process of sharing that charging power between the vehicle's starter battery and a secondary battery. A split charge relay acts just like a switch and is installed in line between the two batteries. The advantage of using the split charge relay is its automatic operation with very small contact wear outs and it is a much simpler installation. DAMA WM686 relay has a little risk of contacts arcing and so protects against ignition (This is much more important on boats where gas or petrol fume build-up is a concern)
DAMA WM686 relay is very popular in a campervan or boat to allow a secondary battery (i.e. leisure) to automatically charge whenever the engine is running. It is also popular for installing the automatic car starting system.
