The Enerdrive EN-VSR1224-140 140A Voltage Sensitive Relay (VSR) allows safe charging and separation of starting and auxiliary batteries in Marine, 4WD, Caravan and Solar applications. It's perfect for those situations where you have tow batteries and you need start assist between them.
The ePOWER VSR or voltage sensitive relay is essential for systems that utilises more than one battery. When the engine is started, starting & auxiliary batteries are separated allowing only the starting battery to be charged. When the charge voltage reaches 13.2 Volts the VSR engages allowing both starting and auxiliary batteries to be charged. When the engine is stopped and the battery voltage falls below 12.8 Volts the VSR disengages separating the start and auxiliary batteries. The auxiliary battery continues to power any accessories without risk of draining the starting battery.
Additionally, the ePOWER VSR range offers features like:
• No voltage loss
• Intelligent battery monitoring to prevent unwanted switching
• Starter battery priority
• Bipolar switching
• Voltage dependent switching
• Camper vans
