Digital Display Voltage Sensitive Split Charge Relay VSR 12V 140A Camper Car RV Yacht Smart Dual Battery Isolator


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.

Instructions: When the voltage of the main battery is greater than 13.3V, the main battery will charge the secondary battery. When the voltage of the main battery is lower than 12.7∨, the main battery is disconnected from the secondary battery.

Features of 12V 140Amp Voltage Sensitive Relay VSR Dual Smart Battery Isolator

【Manual State Function】:Long Press the button for 3 seconds, the BLUE led will be On, and the manual mode is on. Press the button each time, you can complete the circuit connection and disconnection. Circuit switched on the red indicator, voltmeter lights up at the same time. Switched off the red indicator, voltmeter lights off.

【Auto State Function】:Long press the button for 3 button again, the BLUE led will be Off, the Auto mode is on. Voltage exceed 13.3V: Circuit will be automatically connected. Voltmeter & Indicator ON. Voltmeter lower than 12.7V: Circuit will be automatically disconnected. Voltmeter & Indicator Off.

【Voltage Display】:This dual battery isolator is constructed with a voltmeter which will display the real-time voltage. If you connect 2 batteries, then the voltmeter will display the battery that has high voltage. The smart battery isolator is universal fit for truck, UTV/ATV, boat, marine, bus, etc.
【Voltage Sensitive Relay】:Cut-in voltage: 13.3V and Cut-out voltage: 12.8V. Ensure the main battery is always charged so that you won’t worry about the the battery will drain out and stuck on the road. Very convenient and safe to use.

【Voltage Protection】:Input voltage lower than 11V or Input voltage more than 17V: Circuit will be automatically disconnected so as to protect the main battery from over discharging.


Application of 12V 140Amp Voltage Sensitive Relay VSR Dual Smart Battery Isolator

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. There are also applications in the industrial field.
