The REDARC Smart Start® SBI12D is a microprocessor-controlled battery isolator designed for use in dual battery systems. Functioning as a solenoid priority system, it safeguards the start battery from excessive discharge. Operating at 12 volts DC, the SBI12D provides a continuous rating of 100A.
Dual Sensing: The dual sensing model is employed to effectively isolate the start and auxiliary batteries in a system where the auxiliary battery may also receive a charge from an external source, such as solar panels or an external AC battery charger. The SBI12D additionally enables the start battery to be charged by the external source once the auxiliary battery reaches 13.2 volts, facilitating the top-up of the start battery.
Power Saving Technology: Incorporating advanced electronic components, the Smart Start SBI12D prevents the solenoid from generating high voltage transients. Offering an advantage over diode battery isolators by eliminating the voltage drop associated with diode-type isolation, it also includes sophisticated fault detection and LED indication of operation. This warns users of faults such as over-voltage, voltage drop, and excessive current draw conditions.
Primarily used in 4WD and commercial vehicles, the Smart Start SBI12D provides a secure method for charging an auxiliary battery.
