Voltage Sensitive Relay Single Sense 12V 140A (Smart Battery Isolator)

Description

Voltage Sensitive Relays have been specifically designed for a wide variety of 12V applications. The Voltage Sensitive Relay 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 Voltage Sensitive Relay also feature surge protection and a L.E.D indicator designed to alert the user when the unit is engaged. Voltage Sensitive Relay 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. This is a single sense unit, in which the Voltage Sensitive Relay will only respond to voltage change at the red-dot terminal.
