It features a low standby current draw and sophisticated fault detection and LED indication of operation to warn the user of faults including over-voltage, voltage drop and excessive current draw conditions. It is better than a diode battery isolator due to the voltage drop associated with diode type isolation. The battery isolator is primarily used in 4WD and commercial vehicles and incorporates electronic components that will prevent the solenoid from generating high voltage transients. The SBI2 provides 12 volt DC incorporating 100A of continuous ratings. It will protect the start battery from excessive discharge, whilst allowing the auxiliary battery to supply non-essential loads. This Voltage Sensitive Relay (VSR) kit provides everything you need to wire up your second battery, while handling the isolation during shut-off periods. BUY WITH CONFIDENCE: Every 140 Amp Dual Battery Isolator is backed by an industry leading 12-month warranty.The REDARC Smart Start® SBI2 is a microprocessor-controlled battery isolator used in dual battery systems as a solenoid priority system.
#Smart battery isolator wiring install
Easy-to-follow directions for the novice DIYer to install this on their favorite ATV/UTV based application. Installation of the Battery Isolator Connection Disconnect the negative battery cable (Earth) from the vehicles starting battery. No diode efficiency losses and reduces charging system workload by not connecting. 3-wire install and comes with mounting plate, hardware, heavy gauge ground and power wires (see images for exact contents of kit). The Smart Battery Isolators are smaller, lighter, less heat generated. WHAT YOU GET: 140 Amp Smart Battery Isolator 7AWG x 12” Red Cable with two connectors 3AWG x 12” Black Cable with two connectors 7AWG x 24” Red Cable (cut to length, with single connector) (1) 5/16” Lug Cable End, (1) 3/8” Lug Cable End 1-1 ½” Red Shrink Tube.
One terminal on the relay should be connected to the positive terminal of the primary starting battery using 6ga red wire. Every piece of wiring should be secured as you go with cable ties. This wire is simply used as a ground for activating the relay. Wrap each cable with corrugated split tubing, and heat shrink the terminal ends.
#Smart battery isolator wiring manual
Includes manual overide function which allows you to link two batteries. Automatic separation and connection of the Main (Starting) battery in. The black wire coiled inside the relay needs terminated to a good ground location using the included blue crimp connector. This International Protection rating means that your KeyLine isolator is safe for use even for your off-road needs in dusty, wet and unexpected extreme weather environments. The Smart Battery Isolator monitors the main starter batterys voltage voltage. Isolator switches off to prevent dead battery if start. RUGGED DURABILITY: Unlike other chargers on the market today, the KeyLine Automatic 140 Amp Dual Battery Isolator is IP65 Certified. This 100-amp dual-battery isolator pulls power from your start battery to charge your auxiliary battery.It's like having two separate power sources for each battery while only having one alternator!
Disconnect the battery or switch it off with the 2. Voltage Sensitive Relay (VSR) cuts in at 13.3 volts and cuts out at 12.8 volts to ensure your primary battery is always charged and ready to start your vehicle. 48525,30 Smart Battery Isolator, Install Guide Datasheet by Littelfuse Inc.
