Functional description:
Note the positive and negative polarity and power supply voltage, connected to the power supply fan can be used, potentiometer counterclockwise to the end off, clockwise to the end for the maximum output
A separate small adjustable resistor on the board (starting speed adjustment) is used to adjust the speed of just open position
If the fan speed changes in the opposite direction of the adjustment, the fan is a reverse timing fan, the (PF) set point needs to be shorted with solder, the operation must first power off to avoid damage! After shorting the PWM signal becomes reverse change with the adjustment, then the reverse timing fan can achieve positive adjustment
Caution.
This is a four-wire PWM fan speed controller, can only control 12V four-wire fans that support PWM speed control, such as many 12V four-wire chassis or CPU fans, is not able to control 2-3 wire fans
