製品パラメータ：

Operating voltage: DC12V (can work in 8-15V voltage, please note that the fan voltage is consistent)

Fan current: not more than 3A This current is limited by the switch and connector, you can take a separate power cord expansion

Circuit board loss: not connected to the fan less than 20mA

PWM signal mode: 5V25KHZ

PWM signal output range: 0% – 100%

Start position PWM adjustment range: 0% -60

Input type: red and black line/2510-3P output optional

Output interface type: 2510-4P mismatch, conventional CPU, chassis fan socket, pin spacing 2.54mm

 

Function Description:

Pay attention to the positive and negative poles and power supply voltage, connect the power supply fan can be used, potentiometer counterclockwise to the end of the closure, clockwise to the end of the maximum output

Separate small adjustable resistor on the board (starting speed adjustment) is used to adjust the speed of the just turned on position.

If the fan speed changes in the opposite direction to the adjustment direction, it means that the fan is a reverse timing fan, you need to short the (PF) set point with solder, be sure to disconnect the power first to avoid damage during operation! After shorting, the PWM signal will change in the reverse direction with the adjustment, then the reverse timing fan can realize the forward adjustment.

 

注意：

This is a four-wire PWM fan speed controller, can only control 12V support PWM speed four-wire fan, such as many 12V four-wire chassis or CPU fan, is not able to control the 2-3 line fan!
