Automatic Offroad Electric Cooling Fan Dis-abler

Micro controlled device to disable the electric cooling fan when you are entering water in a off road vehicle. Thus preventing the fan from crashing into the radiator when the fan is under full power.

  • Redundant safety to keep the fan running fully, if the device fails.
  • Very low current draw when in operation.
  • Indication LED to show fan on/off state.
  • Watch Dog enabled to keep the microcontroller from locking up.
