Product parametersWorking voltage DC12V can work under 8-15V voltage pay attention to the same fan voltage Fan current no more than 3A this current is limited by switches and connectors and can be expanded by power lines alone Loss of circuit board itself less than 20mA without fan PWM signal mode 5V25KHZ
PWM signal output range 0%-100% position PWM adjustment range 0%-60% Output interface model 2510-4P dislocation conventional CPU chassis fan socket pin spacing 254mm

Function Description
Pay attention to the positive and negative poles and the power supply voltage After the power supply fan is connected it can be used The potentiometer is turned off counterclockwise to and the clockwise end is the maximum output
A separate small adjustable resistor starting speed adjustment on the board is used to adjust the speed of the just-open position
If the speed change of the fan is opposite to the adjustment direction it means that the fan is a reverse-sequence fan and the PF setting point needs to be short-circuited with solder and the power must be cut off operation to avoid damage The short-circuited PWM signal changes in the reverse direction with the adjustment and the reverse-sequence fan can realize forward adjustment
Precautions
This is a four-wire PWM fan speed controller It can only control 12V four-wire fans that support PWM speed regulation For example many 12V four-wire chassis or CPU fans cannot control 2-3-wire fans
