DC 12V PWM Speed Controller Fan Speed Governor 4 Wire Computer Temperature Controller Switch for PC CPU Cooler Electronic Kit
Feature:
Using high-quality materials, quality is guaranteed
With switch, can be turned off
The product has exquisite appearance
Simple and convenient wiring
Stable performance
Product parameters:
Working voltage: DC12V (can work at 8-15V voltage, please note that the fan voltage is consistent)
Fan current: no more than 3A This current is limited by the switch and connector, and can be expanded by the power line alone
The circuit board's own loss: less than 20mA without a fan
PWM signal mode: 5V25KHZ
PWM signal output range: 0%-100%
Starting position PWM adjustment range: 0%-60%
Input type: red and black wire/2510-3P output optional
Output interface model: 2510-4P offset, conventional CPU, chassis fan socket, pin spacing 2.54mm
Function description:
Pay attention to the positive and negative poles and power supply voltage, and use it after connecting the power supply fan. The potentiometer is turned counterclockwise to the end to close, and clockwise to the end for maximum output
The separate small adjustable resistor on the board (starting speed adjustment) is used to adjust the speed of the just-opened position
If the fan speed changes in the opposite direction of the adjustment direction, it means that the fan is a reverse timing fan, and the (PF) setting point needs to be short-circuited with solder. Be sure to 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 reverse timing fan can achieve positive adjustment
Note:
This is a four-wire PWM fan speed regulator, which can only control 12V four-wire fans that support PWM speed regulation, such as many 12V four-wire chassis or CPU fans, and cannot control 2-3 wire fans
