THE SBI12-LLD
The SBI12-LLD is a microprocessor controlled Load Disconnect Isolator. The SBI12-LLD is designed
specifically for use in LiFePO
4
battery applications as a system to protect the lithium 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.
RECOMMENDED FUSES & CABLING
Suitably sized Wire and fuses for the connected loads should be used. REDARC recommend using MIDI
fuses along with a quality fuse holder to match. The diagram below shows the construction of a MIDI
fuse installation (cables not included).
REDARC offer MIDI fuse kits containing the required fuses, fuse holders, crimps and nuts:
