Voltage Sensitive Relay - 12V 140A

A Voltage Sensitive Relay (VSR) allows two batteries to be charged at the same time. When the engine is on and the starter battery reaches 13.3 Volts, the VSR will engage, allowing the starter and leisure batteries to charge. When the voltage drops below 12.8 Volts, the VSR disengages, separating the batteries. This system eliminates the risk of draining the starter battery accidentally and also protects sensitive electronic equipment powered by the leisure battery from being harmed by engine start up spikes.

Dual Voltage Sensing Technology - allows the leisure battery to be charged from the starter battery when the alternator is running and also allowing charging from the leisure battery to starter battery when charging the battery from the mains.
