ML-RBS Remote Battery Switch with Manual Control Auto-Release - 12V

The Blue Sea 7713 ML-RBS is our favorite low current draw (13mA when ON) high amperage (500A continuous) battery switch. It can also be used with a LiFePO4 BMS that uses standard 12V+ NO/NC switching. Apply +12V to the red wire and it closes. Remove +12V power from the small red wire and it opens. No more fiddling around with trying to convert an NO/NC BMS output to a "pulse" for a typical ML magnetic latching switch. This 7713 also features a manual over-ride switch. Unlike a typical magnetic latching relay, if power is lost, it reverts to OFF/OPEN or fails safely. This is the safe approach for any BMS. This is, by a long shot, the lowest ON or OFF state consumption electronic switch made today.


IMPORTANT LI-ION BMS NOTE: If your BMS pulls the relay contacts to ground, top operate a relay, then you will need to invert this signal in order to use the 7713

FEATURES:

  • Manual override knob provides an added level of safety allowing control with or without power and offering LOCKED OFF capability for servicing
  • LED output to remotely indicate switch state - requires optional LED
  • 3/ 8"-16 tin-plated copper studs for maximum conductivity and corrosion resistance
  • 7/ 8" (22mm) stud length accepts multiple cable terminals
  • Label recesses for circuit identification
  • Silver alloy contacts provide high reliability for switching live loads
Auto Releasing ML-Series Remote Battery Switch with SPST Switching Provides 500A switching and features of current ML Remote Battery Switches, but can be controlled with SPST or SPDT switch for applications where a normally open relay is desired
