🏻This is a four-wire PWM fan speed controller. It can only control 12V four-wire fans that support PWM speed control. For example, many 12V four-wire case or CPU fans cannot control 2-3-wire fans.
🏻Consumption less than 20mA without fan PWM signal model 0-5V 25kHz PWM signal output range 0% to 100% start of PWM setting range 0% to 60% output interface 2510-4P, 2.54mm distance size 26x20mm, button. 15. mm, installation opening: 7 mm
Pay attention to the positive and negative poles and the supply voltage. After the power supply fan is connected, it can be used. The potentiometer is turned off counterclockwise to the end, and the end clockwise is the maximum power. A separate small adjustable resistor (initial speed setting) on the board is used to adjust the speed of the just open position.
If the speed of the fan changes and the adjustment direction is opposite, this means that the fan is a reverse runner. The setting point (PF) must be short-circuited with solder and the power supply must be switched off before operation to avoid damage! The short-circuited PWM signal changes in the reverse direction with the setting, and the reverse runner can realize forward adjustment.
