Redarc SBI12-BLD BMS Load Disconnect Isolator

The SBI12-BLD is used in conjunction with a Redarc Manager15 or Manager30 BMS in a 12v negative ground automotive system 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 make sure reliable solenoid engagement.

The SBI12-BLD spec sheet lists maximum inrush current 400A, maximum continuous current 100A, turn on voltage 10.2V, turn off voltage 10V, turn on delay 5 seconds, turn off delay 10 seconds. It measures 75 x 70 x 80 mm (width x height x length), and it weighs 200 g.
