Features: The ESC is specially developed for various industrial control power tools such as air pumps, water pumps, oil pumps, fans, etc. that use DC three-phase brushless motors. By default, the medium-advance angle works for a long time and high current. When the external heat dissipation conditions of the ESC are poor, the power is automatically reduced when the temperature exceeds 100 degrees, and the temperature drops to 100 degrees and returns to normal.

Precautions:

1. There is no fuse on the power supply circuit on the motherboard. Jianyi added it. Connecting the positive and negative poles of the power supply will cause permanent damage to some of the chips on the board (even 1 second).

2. There is motor stall protection during normal operation. Because the module power current is very large, please do not artificially short circuit when the module is not working normally. Once the short circuit may burn the line and burst the tube, please use a small Current low voltage test, after ok, then work with high current and high voltage.

3. Do not connect a motor that is obviously inconsistent with the voltage, current and power of the drive module, or far apart，to avoid the inexplicable damage.
