REDARC Smart Start SBI Battery Isolator - 24V 200A

The REDARC Smart Start SBI224 protects the start battery from excessive discharge while the auxiliary battery is supplying non-essential loads in dual battery systems. The SBI224 provides 24 volt DC incorporating 200A of continuous ratings. The 200A battery isolator is suited best for heavy-duty operations. The Smart Start SBI224 battery isolator is mostly used in commercial vehicle dual battery systems. It incorporates electronic components preventing the solenoid from generating high voltage transients. It's used instead of a diode battery isolator due to reduced voltage drop associated with diode type isolation. Sophisticated fault detection and LED indication of operation warns the user of faults including over-voltage, voltage drop, and excessive current draw conditions. The Smart Start SBI224 battery isolator is a safe way to charge heavy-duty dual battery systems.

Reference Information

Battery Isolator 24V200A

REDARC Smart Start battery isolators are commonly used in 4WD and commercial vehicles. They incorporate electronic components that prevents the solenoid from generating high voltage transients. Due to the voltage drop associated with diode type isolation, it's better than a diode battery isolator. A low standby current draw, fault detection, and LED indication of operation warns users of faults such as voltage drops, over-voltage, and excessive current draw conditions. Safely maintain the charge your dual battery system with the REDARC Smart Start battery isolators.
