Battery Selectors & Battery Disconnect Switches 1211-31
Model ID：1211-31
Voltage Sensitive Relay
Rating: 12VDC, 140Amps
The voltage sensitive relay allows 2 batteries to be charged at the same time. When the engine is started and the start battery reaches 13.7 volts, the VSR engages, allowing 2 battery banks (start and house) to be charged simultaneously. When the voltage drops below 12.8 volts ( ex the engine is stopped), the VSR disengages, separating the batteries.
This system eliminates the possibility of draining the wrong battery and protects sensitive electronic equipment powered from the house battery from harmful engine start up spikes.
