Overview:

The single-channel PWM fan control board adopts the PWM speed regulation scheme, which can better adapt to the 4-wire speed regulation fans the market.

By rotating the potentiometer, the fan speed can be easily adjusted.

1. The PWM frequency is 25KHZ, which can adapt to most 12V adjustable speed fans the market.

2. The duty cycle can be adjusted from 0% to 97%, and the speed regulation range is wide.

3. Rotary potentiometer with , easy to start and stop.

4. Input voltage: 12V

5. Small size, easy to install

Instructions for use:

Need to solder the wire by yourself, connect to 12V voltage, pay attention to the wiring sequence from top to bottom, 1 pin is grounded, 2 pin is connected to 12V, and 3 pin is left blank.

Rotate the potentiometer, turn the , the red led will light , which means the power supply is normal. Continue to adjust the potentiometer clockwise, and the fan speed will gradually increase.
