VSR & Voltmeter
-
A Voltage Sensitive Relay (VSR) allows two batteries to be charged at the same time. When the engine is started and the start battery reaches 13.7 volts, the VSR engages, allowing two battery banks (start and auxiliary) to be charged simultaneously.
-
12 Volt 140 Amp
-
13.3v - 12.8v
-
Continuous Current Rating 125A
-
Intermittent Current Rating 140A
-
Power Consumption 10mA ( Standby )
-
330mA ( Engage ) 0mA ( Storage Mode )
HULK 4x4 Dual Battery Isolators / Voltage Sensitive Relays have been specifically designed for a wide range of 12V applications.
HULK 4x4 Dual Battery sense the input voltage generated and automatically content / 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, Dual Battery Isolators also feature surge protection and a L.E.D indicator designed to alert the user when the unit is engaged.
HULK 4x4 Dual Battery Isolators 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 and ready to go.
