Featuring dual sensing technology, it supports charging from vehicle alternators, solar panels, or mains chargers, making it an essential upgrade for camper vans, motorhomes, 4x4s, caravans, and boats seeking reliable power management without complex wiring. ## Description HC Cargo Voltage Sense 140ampIntelligent RelayThe voltage sense relay simply detects the rise in voltage fromyou vehicles charging system when it exceeds 13.3v to allow you tocharge your leisure battery(s) while your engine is running. Whenyour engine is switched off and the battery voltage drops below 12.8vthe relay will isolate your leisure battery(s) from your main starterbattery so it does not drain your main starter battery and you willalways 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 mainscharger or solar panel is applied to the leisure battery that exceedsthe relay activation voltage of 13.3v it will activate the relay toallow this charging device to also maintain the starter battery.Additional InformationRelay activation voltage 13.3vRelay isolation Voltage 12.8vDuel sense operationVoltage 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 chargingvehicles with Euro cat 5&6 engines you may need to use a DC to DCcharger Review: Installed and works. - Not much to say, it works.
