Description

Size:R12140B

THANK YOU FOR PURCHASING OUR BATTERY ISOLATOR

INTRODUCTION
Automatic separation and connection of tho main (starting) battery in parallel with auxiliary battery according to the voltage of level of the main battery. This isolator will constantly scan the main battery voltage level for connection and charging of tho auxiliary battery to the main battery for charging.

FEATURES
-Designed for dual battery systems
-Suitable for most 12V/24V charging systems
-Surge protect
-Automatically sensing voltage level of main battery

HOW DOES IT WORK
l. When the engine is started and the voltage of start battery is higher than Gut-in volts, the smart battery isolator(SBI) assists in keeping engaging,two batteries(startand house) are charged concurrently.Unit Indicator(LED) is on.
2.When the engine is stopped, the batteries no longer have a charge from the alternator, and the loads connected with the batteries begin to deplite them.Unit Indicator(LED) is on.
3.When the voltage drops below cut-out volts for 5 seconds. the SBI senses it and disengages,separating both batteries.This can save power of your start battery from being drained by over loads on house battery. Unit Indicator(LED) is off.
4.When the vehicle restarted, the start battery has enough power to crank the engine, and the engine is powering the alternator, when the start battery has reached the cut-in volts, the SBI engaged again.Unit Indicator(LED) is on.

INTENDED APPLICATIONS
Caravan, 4WD, marine, vehicle with second battery.

WARNING
Never use the battery isolator in a location with possibility of gas or dust explosions.
Proper and correct connections and safety features will have to be followed according to local applicable regulations.
Use suitable sized cables and connectors.
Use reliable terminals and torque the bolts tightly.
