RVK 120 - Voltage Sensitive Relay For Engine Charging

Our price $117.31

The Voltage Sensitive Relay allows two 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 two battery banks (start and house) to be charged simultaneously.

When the voltage drops below 12.8 volts (eg the engine is stopped), the Voltage Sensitive Relay disengages, separating the batteries.

The system eliminates the possibility of draining the start battery and protects sensitive electronic equipment powered from the house battery from harmful engine start up spikes.

Voltage: 12VDC
Engages: 13.7VDC

Dimensions: 69 x 69 x 50mm
