Voltage Sensitive Relay 24v 100A (Pack of 1)

This 24V voltage sensitive relay (VSR) lets you charge two separate battery banks from one charging source, such as a vehicle alternator, without flattening your main battery. It suits split charging systems in vehicles and marine applications.

The VSR monitors the main battery voltage and only connects the secondary bank to the charging source once the main bank is fully charged, so the secondary bank can never drain the main bank. Its dual sense function reads the voltage of both connected batteries and activates if either one is receiving a charge. This means the second battery can also be charged from an external battery charger or a second charging source.

Fitting: The main and auxiliary batteries can be connected to either terminal. The VSR's MCU automatically detects which is the main battery and which is the auxiliary, and charges each as required. Connect the small black wire to earth.
