Switching the positive and negative poles of the power supply on the motherboard will cause permanent damage to some of the chips on the board the power will not work for a few seconds2. There is a sampling overcurrent protection at the motor output during normal operation. Since the power and current of the module are large, do not artificially shortcircuit the module when the module is not working normally. When the short circuit occurs, the circuit may be burned and the tube may burst, the first wiring test Please test with low current and low voltage. After ok, connect with high current and high voltage. Since it is a bare circuit board module, pay attention to the insulation of the wiring head. It is strictly forbidden to touch the circuit board parts3. Do not connect the motor that is obviously inconsistent with the module voltage, current or power to avoid uneplained damageModel Number Motor Drive BoardColor As shownMaterial Plastic MetalPackage contents1 DC 624V 1000W BLDC 3Phase Brushless Motor DriverOnly the above package contents, other products are not included.Note Light and different displays may cause the color of the item in the picture to be slightly different from the real thing.
