It is a PWM fan control board.The PWM fan control board adopts the PWM speed regulation scheme,which can better adapt to the 4-wire speed regulation fans on 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 on the market.
2).The duty cycle of the fan speed controller can be adjusted from 0% to 97%,and the speed regulation range is wide.
3).Rotary potentiometer with switch,easy to start and stop.
4).The fan speed controller is small and easy to install.
1).Product Name:PWM Fan Control Board
5).Adapt to the Fan:12V adjustable speed fan
4.Instructions for Use:
1).It needs to solder the wire by itself and connect to the 12V voltage.Pay attention to the wiring sequence from top to bottom.Pin 1 is grounded,pin 2 is connected to 12V,and pin 3 is not connected.
2).Rotate the potentiometer,turn on the switch,the red led will light up,which means the power supply is normal.
