DC5-12V manual 4-wire PWM fan governor with switch chassis 4-wire fan speed regulation and noise reduction can be turned off

Description:      

Color classification: with red and black wires, 3P plug wires

Features:

1. Support DC5-12V wide voltage input range, suitable for a variety of equipment with different voltage needs

High flexibility of use

2. The fan speed control is realized through manual adjustment, which is more convenient to use 3. With the switch function, the user can directly control the start and stop of the fan, which is convenient and fast, and effectively prolongs the life of the fan and equipment

4. Using advanced PWM speed regulation technology, it can not only reduce the noise of the fan when running, but also maintain a good heat dissipation effect at low speed, creating a quieter working or living environment

Pay attention to the positive and negative poles and power supply voltage, you can use it after connecting the power fan, the potentiometer is turned off counterclockwise, and clockwise is the maximum output. If the speed of the fan changes in the opposite direction of adjustment, it means that the fan is an anti-timing fan, and the (PF) setting point needs to be shorted with solder, and the power must be turned off first to avoid damage! After the short circuit, the PWM signal changes in the opposite direction with the adjustment, and the reverse timing fan can be adjusted in the forward direction
