Specification: Type Voltage Sensitive Relay Continuous Current 140A Max Current 160A Current Draw - Charging 280mA Current Draw - Standby 8mA Disengage delay 5-10 Seconds Recommended Fuse 80Amp Power Studs M6 Stainless Steel Surge Protection Built-in Dimensions 70x52x70 mm More Information: 1.When the engine is started, the starting and auxiliary batteries are separated allowing only the starting battery to be charged. When the charge voltage reaches 13.3 volts the VSR engages allowing both starting and auxiliary batteries to be charged. This is indicated by the red light in the top LH corner being illuminated. 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. 2.This VSR is Dual Sensing which senses the voltage of both batteries.This is very useful in that being Dual Sensing bi directional , you have a battery charger or solar power connected to your auxiliary battery and this battery gets charged enough to the VSR's set points , the VSR then will allow your charging source to back charge the cranking battery as well bringing that to fully charged as well but again, if the voltage drops below 12.8 volts, the VSR will again disconnect isolate the batteries. Package Included: 1 X 12V 140A Voltage Sensitive Relay Cables and Accessories
