Overview

REDARC BMS Load Disconnect Isolators

REDARC offers BMS load disconnect isolators for standard or lithium batteries. Here are the differences:

* Model SBI12-BLD is used in conjunction with a REDARC Manager30 Battery Management System (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.

* Model SBI12-LLD is a microprocessor-controlled load disconnect isolator. It's designed for use in lithium battery applications (LiFePO4) as a system to protect the battery from being excessively discharged by auxiliary loads, enabling the auxiliary battery to remain above the level at which internal protection circuitry would activate. Falling below this threshold would prevent many chargers from recharging the battery. Put simply, once the auxiliary battery has been overly discharged, the load disconnect isolator will turn off any connected loads. Similarly, if the battery climbs back above a suitable level, the Load Disconnect Isolator will restore power to the connected loads.

Voltage spike protection:

Both smart start battery isolators incorporate a number of spike protection components specifically designed to reduce the risk of damaging the unit, and are designed to prevent any spikes generated by the solenoid coil from affecting vehicle equipment.

Features:

* Overmold design
* Compact in size and easy to install
* Silver contacts for longer life and suitable for marine applications
* Power saving technology
* Fault indication
* Fully surge protected
