Protection mechanism of the Scanner RC SCS-40A to SCS-110A+HS speed controllers.

1.The Scanner RC ESC has 2 build in protection, first is watt out put limit, the output is rated at 388watt, at this output every thing will work on continues bases, and at approximately 410watts to 420 watts it will automatically shutdown the output to the motor, as long as the motor is not rate too much over the ESC spec limits, this safety mechanism will prevent a over load to the ESC but if you install a motor for example rate at 1000watts, this mechanism will not work properly due to the instant surge of power demand from the motor, it may shutdown too early or simply fry the ESC, the only solution to this is to never use a Motor that has a rating bigger then the ESC, don’t even thing you can use it if you run the motor at a slower RPM or load, it will not work!!

2. The second protection is based on temperatures, at 95 degree C, the ESC will slowdown the power output to the motor by 50% (  the on board LED will turn on), to re go in to full throttle you need to move the throttle stick to idle position and then the ESC will resume normal out put one’s you throttle up again.

Their will be a warning in the manual, and we will clearly state the ESC is rated at a particular watts, not sure why all the other ESC makers don’t do this, but we will do it.
