Item Description

UniSquare Item ID Number:

Voltage Sensitive Relays have been specifically designed for a wide variety of 12V applications.

The VSR units sense the input voltage generated and automatically connect/disconnect the appliance or circuit at pre-set voltages, eliminating the possibility of discharging the primary starting battery. Constructed with a weatherproof body (IP65) and durable silver tipped contacts, the VSR units also feature surge protection and a L.E.D indicator designed to alert the user when the unit is engaged.

This is a Dual Sensing VSR means that the VSR will combine if EITHER side is higher than 13.3V. Usually the secondary side could be connected to EITHER a charger or a solar panel to provide the charging voltage. There will be no red dot on the terminal as both side can sense voltage independently.

VSR units are ideal for dual battery set-ups as they enable two batteries to be charged at the same time and then isolates the batteries from each other when the vehicle is turned off, ensuring your starting battery is always charged & ready to go.
