ENERDRIVE VOLTAGE SENSITIVE RELAY 12V VSR ISOLATOR 140A DUAL BATTERY SYSTEM
The Enerdrive Voltage Sensitive Relay (VSR) allows safe charging and separation of starting and auxiliary batteries in Marine, 4WD, Caravan and Solar applications, 12 Volts, 140A continuous, Water Proof ( IP65 ).
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.
The Enerdrive 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 Enerdrive VSR’s set points , the Enerdrive 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 Enerdrive VSR will again disconnect (isolate) the batteries.
Enerdrive voltage Sensitive Relays (VSRs) are suitable for a wide variety of DC applications. VSRs sense the input voltage and automatically connect/disconnect the appliance or circuit at the set voltages. The cut-out has a 5 second delay preventing the relay from disconnecting during a momentary drop in voltage.
