VOLTAGE SENSITIVE RELAYS

Battek Battery Management SystemVoltage Sensitive Relay Series

Voltage Sensitive Relays have been speci�cally designed for a wide variety of automotive, truck and marine applications.

�e VSR units sense the input voltage generated and automati-cally 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.

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 o�, ensur-ing your starting battery is always charged & ready to go.

Features:

- Designed for dual battery systems- Suitable for most 12V charging systems- Surge protection- Easy to install- Automatically sensing voltage level of main battery- Cut In Voltage: 13.3V- Cut Out Voltage: 12.8V- CE Certi�ed
