Specifications
Continuous : 120 Amps
Intermittent : 140 Amps
Sense : Dual
Voltage System : 12VDC
Cut in/cut out 13.7/12.8VDC
VSR OPERATION
The voltage sensitive relay (VRS) allows two batteries to be charged at the same time. When the engine is started and the battery reaches 13.7 volts, the VSR engages, allowing two battery banks to be charged simultaneously. When the voltage drops below 12.8 volts ( eg the engine is stopped) , the VSR disengages, separating the batteries.
The system eliminates the possibility of draining the wrong battery & protects sensitive electronic equipment powered from the house battery from harmful engine start up spikes.
