![]() ![]() ![]() There is a delay built in to the VSR which means it can take up to 15 seconds for the VSR to connect or disconnect. The negative wire will run from the Starter Battery terminal through to the Auxiliary Battery either directly or via the vehicles chassis. IMPORTANTNOTES It is recommended that a 50 Amp fuse is installed between the Starter Battery and the VSR. Connect the thin black earth wire to either the vehicle chassis or the Start Battery's negative terminal. ![]() Connect the (+) positive wire going to the Auxiliary Battery's positive terminal to the other terminal on the VSR. Connect the (+) positive wire from the Start Battery to the terminal on the VSR marked Main. Installation of Monitoring Mini Voltage Sensitive VSR Relay Dual Battery Controller Isolator 12V 50AMPġ. Once the vehicle system is turned off, two batteries will be disconnected at 12.8 volts after 15 seconds, allowing your main battery to restart the safety of the main battery. This means that both batteries are connected and the system is running. When the VSR connection and disconnecting the auxiliary battery and the starting battery engine according to the current charging level, when the battery starts at 13.2 volts, the VSR will start after 15 seconds, and the LED light is on. Working Principle of Monitoring Mini Voltage Sensitive VSR Relay Dual Battery Controller Isolator 12V 50AMP There are also applications in the industrial field. The battery isolator is mainly used in off -road vehicles, RVs, or other special vehicles that need to add more electric equipment, special use vehicles. 100% SATISFACTION: no reason for return or change.Īpplication of 12V 140Amp Voltage Sensitive Relay VSR Dual Smart Battery Isolator Heavy Duty: this voltage sensitive relay is heavy built to suitable for almost anywhere even off-road, which is water resistant, shock resistant, dust proof and withstand unexpected extreme weather environments.Ĭompatible: used for DC 12 V two battery systems isolate and charge, universal used for car, vehicle, RV, ATV, UTV and boat, also two battery electrical equipment.Įasy to use: this VSR comes with mounting plate and 4 bolts for install. Ensure your primary battery is always charged and ready to start your engine, the secondary will be charged after the primary battery's volts exceed 13.3 volts. Primary Battery Protected: cuts in at 13.3 volts and cuts out at 12.8 volts. Purpose: this voltage sensitive relay is design for two battery systems (SUITABLE for Acid-Lead batteries, NOT SUITABLE for Lithium batteries), allow to having two separate power sources while charging by one alternator, it's all need to charge and isolate two battery systems. When the voltage of the main battery is lower than 12.7∨, the main battery is disconnected from the secondary battery.Ĭut In 3-5 Seconds / Disconnect 3-5 Secondsįeatures of 12V 140Amp Voltage Sensitive Relay VSR Dual Smart Battery Isolator Instructions: When the voltage of the main battery is greater than 13.3V, the main battery will charge the secondary battery. Upgraded version 1.5 dual battery isolator adopts imported power management chip, with novel electronic circuit intelligent automatic management function, and has the characteristics of strong water resistance, low loss, good heat dissipation, high efficiency. 12V 140Amp Voltage Sensitive Relay VSR Dual Smart Battery Isolator for Car Vehicle RV ATV UTV Boat ![]()
