• The relay simply detects the rise in voltage from the vehicles charging system when the engine is started to allow power to charge your second/leisure battery.
• Suitable for all Camper vans, Motor homes, Caravans, 4x4s and Boats.
• Duel sense operation
• Relay activation voltage 13.3v - Relay isolation Voltage 12.65v

Durite 0-727-33 Voltage Sense 140amp Intelligent Relay The voltage sense relay simply detects the rise in voltage from you vehicles charging system when it exceeds 13.3v to allow you to charge your leisure battery(s) while your engine is running. Whe nyour engine is switched off and the battery voltage drops below 12.65v the relay will isolate your leisure battery(s) from your main starter battery so it does not drain your main starter battery and you will always be able to start your vehicle. All of the range of 140amp voltage sensitive relays are dualsensing meaning that if a charging voltage like through a mains charger or solar panel is applied to the leisure battery that exceeds the relay activation voltage of 13.3v it will activate the relay toallow this charging device to also maintain the starter battery. Additional Information Relay activation voltage 13.3v Relay isolation Voltage 12.65v Duel sense operation Voltage sense systems are especially suited for modern vehicles asthis type of system does not need an ignition feed or any additionalwiring into your vehicle but for modern Intelligent smart charging vehicles with Euro cat 5&6 engines you may need to use a DC to DCcharger
