Voltage sensing split charge relay wiring diagram.
Allows split charging of second battery bank without discharging the primary start battery.
A range of quality voltage sensing split charge relays from 30 amp relays to 150 amp relays.
A voltage sensitive split charge relay or v s r.
Voltage sensitive sensing relay vsr voltage sensitive relays or vsrs sense the voltage of the starter battery and close the contacts inside the relay at a pre set threshold normally around 13 7v check manufacture s specs.
Once the input voltage reaches a certain level the device uses an electromagnet to pull a set of contacts that make or break a circuit.
140a relay makes at 13 3 volts and breaks at 12 65 volts.
Durite 140amp 12 volt split charge vsr relay 12v voltage sensitive relay 140a 12 volt 140 amp with red led indicator.
The contacts then open again at a pre set lower threshold normally around 12 8v.
Allows charge to flow into one battery or bank of batteries only when a charging voltage is detected at the other battery dual sensing operation.
Select sub category 12volt 180amp 2mtr voltage sensing split charge relay kit 110amp cable.
