The SBI12-BLD is used in conjunction with a REDARC Manager30 BMS to protect the auxiliary battery from excessive discharge. Specifically designed for use as the load disconnect solenoid controlled by the BMS, the black (earth wire) should be connected to the load pin of the BMS.

The BMS sets the turn on and turn off points through its settings and switches this black wire (earth when loads should be on, no earth when loads should be off), and there is additional voltage thresholds monitored by the Smart Start SBI12-BLD to ensure reliable solenoid engagement

  Voltage spike protection

 The SBI12-BLD smart start battery isolator incorporates a number of spike protection components specifically designed to reduce the risk of damaging the unit, and is designed to prevent any spikes generated by the solenoid coil from affecting vehicle equipment.
