The REDARC Smart Start® SBI212 is a battery isolator used as a solenoid priority system to protect that start battery from excessive discharge while the auxiliary battery is supplying non-essential loads. The SBI212 provides 12 volt DC incorporating 200A of continuous ratings, the battery isolator is designed for extremely heavy-duty operations.
Power Saving Technology
Primarily used in commercial vehicle dual battery systems, it incorporates electronic components that will prevent the solenoid from generating high voltage transients. It is better than a diode battery isolator due to the voltage drop associated with diode type isolation. It features a low standby current draw and sophisticated fault detection and LED indication of operation to warn the user of faults including over-voltage, voltage drop and excessive current draw conditions.
The Smart Start SBI battery isolator is a safe way to charge dual battery system and should often be installed with a high quality fuse kit.
