VSR Voltage Sensitive Relay 24v 100A

This simple device allows the charging of two separate battery banks from a single charging source such as vehicle alternator with no risk of flattening your battery bank.

By sensing the main battery voltage, the VSR (voltage sensitive relay) will only connect the secondary bank to the source when the first bank is fully charged. This ensures that the secondary bank can never drain the main bank.

Dual sense allows the unit to sense the voltage of both batteries that it is connected between. If either battery is receiving a charge the VSR will activate. This allows the charging of the second battery from an external battery charger or second charging source.

The VSR can handle charging currents up to 100A with zero voltage drop, no moving parts and encapsulated design makes it suitable for marine applications as well as split charging systems in vehicles.
