The REDARC Smart Start® SBI24D is a dual battery isolator designed to isolate the start and auxiliary batteries in a dual battery system, preventing the secondary battery from draining the primary battery. Operating at 24 volts DC, the SBI24D provides a continuous rating of 100A.
Dual Sensing: The dual sensing model efficiently isolates the start and auxiliary batteries in a system where the auxiliary battery may also be charged by external sources like solar panels or an external AC battery charger. Additionally, the SBI24D allows the start battery to be replenished and charged from the auxiliary battery when the auxiliary battery is being charged by an external source, once it reaches 26.4 volts.
Power Saving Technology: The Smart Start SBI24D employs advanced microprocessor-controlled battery isolator technology with electronic components that prevent the solenoid from generating high voltage transients. This technology surpasses diode battery isolators by eliminating the voltage drop associated with diode-type isolation. The isolator also features sophisticated fault detection and LED indication of operation, warning users of faults such as over-voltage, voltage drop, and excessive current draw conditions.
Primarily used in commercial vehicles, the Smart Start SBI24D provides a secure method for charging auxiliary batteries.
