Function Description
Pay attention to the positive and negative poles and the power supply voltage reverse connection will damage the board it can be used after the power supply and fan are connected the potentiometer is turned off counterclockwise to and the clockwise end is the maximum output
A separate small adjustable resistor initial speed adjustment on the board is used to adjust the speed at the just-open position The input of the speed signal port is directly connected to the output of the fan It is mainly used to guide the fan speed signal back to the main board of the device to detect the speed No connection between controller circuits
Precautions
Do not control the fan with more than 1A do not connect the wrong or reverse power supply do a good job of insulation to avoid output short circuit
