BB1210 12V Defeat Circuit Model


BB1210 - 12V to 12V 10A DC DC Charger - BB1210D - defeat circuit model

A BB1225 model with these changes:

  • 10A output current ~140W
  • Works at full power down to 12.0V on main input terminal. Please note that input current shall increase at lower input voltages to maintain output power. We’ve seen it at about 12A at 12.0V input.
  • Reverse charge disabled.
  • Ignition feed connector repurposed to 12V defeat signal to turn BB charging off.
  • When 12V signal disappears, BB starts up again. No noticeable delay (half a second)

Part number for this model is BB1210D
