Redarc Smart Start Load Disconnect Isolator

(8 reviews)

The SBI12-LLD is a microprocessor-controlled Load Disconnect Isolator. The SBI12-LLD is 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. Spike protection The SBI12-LLD Smart Start battery isolator incorporates a number of spike protection components specifically designed to reduce the risk of damaging the unit. It is also designed to prevent any spikes generated by the solenoid coil from affecting vehicle equipment. Features Overmould 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 System Voltage 12V Nominal Turn ON Voltage 11.0V Turn OFF Voltage 10.5V Turn ON Delay 10 sec Turn OFF Delay 2 sec Max. Cont. Current 100 Amps Max.
