Description

The REDARC SBI12 is a 100A 12V microprocessor-controlled battery isolator designed for dual battery systems. It protects the start battery from excessive discharge while allowing an auxiliary battery to power non-essential loads. This isolator functions as a solenoid priority system and offers 100A of continuous current.

It features power-saving technology, including fault detection and LED indication, to alert users to issues like voltage drops or over-current conditions. The SBI12 prevents high voltage transients and offers a lower standby current draw compared to diode battery isolators.
