Simple and convenient control Working voltage: DC5-12V (DC4.7-14V) Fan current: 0.1-1A Fan current is less than 0.1A, the control effect is slightly weak, and more than 1A may damage the board Self-loss, less than 30mA without fan Output position adjustment range: 0% -60% (internal circuit control parameters) Output interface model: 2510-3P, 2.54mm pitch, common processor, chassis fan socket Function description: Pay attention to the positive and negative poles and power supply voltage (reverse connection will damage the board), can be used after connecting the power supply and fan, the potentiometer is turned counterclockwise to the end, and the clockwise end is the maximum output power Separate small adjustable resistor (initial speed adjustment) on the board is used to adjust the speed in the newly opened position. The input of the speed signal port is directly connected to the fan output. It is mainly used to send the fan speed signal back to the device motherboard to set the speed
