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.
Power saving technology
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.
Perfect for heavy-duty dual battery systems
The Smart Start SBI224 battery isolator is a safe way to charge heavy-duty dual battery systems.
