Description

Circuit self-consumption: less than 20mA
PWM signal mode: 5V 25Khz
PWM signal output range: 0%-100%
Starting position PWM adjustment range: 0-60%
Output interface model: 2510-4P offset, conventional CPU/chassis fan socket, pin spacing 2.54mm
Circuit size: circuit board 26mm*20mm, knob screw extends 15mm, installation opening 7mm
Use: It can be used after connecting the power supply and fan. The potentiometer is turned counterclockwise to close, and clockwise to the maximum output.
There is an adjustable resistor on the board to adjust the speed of the open position.
If the fan speed changes in the opposite direction to the adjustment direction, it means that the fan is a reverse timing fan, and the (PF) setting point needs to be short-circuited (please turn off the power before operation to avoid damage).
After the short-circuit, the PWM signal changes in the opposite direction with the adjustment, and the post-timing fan can achieve positive adjustment (the fan cannot be adjusted in the forward and reverse directions).
