Introduction 2
This module is a speed-regulating fan module designed based on the principle of high-frequency switching power supply. The essence is to control the speed of the fan by adjusting the output voltage.
The general USB fan is a 5V direct power fan motor, so the fan speed is fixed, and it is inconvenient to use, and the two-speed fan has an internal booster circuit. When the second gear is turned on, the booster circuit The USB 5V voltage is increased and then the motor is connected, the speed increases, and the air volume becomes larger. Although it can be adjusted, there are only two gears, which is still inconvenient to use. In response to the above problems, our company designed this fan stepless speed regulation module. The input voltage of this module is DC 4~12V, the output voltage changes smoothly between 2.5V~8.0V, the air volume can be set arbitrarily, and the range is wider! And the adjustment is very convenient, just turn the potentiometer, turn clockwise to increase the air volume, turn counterclockwise to decrease the air volume, and the knob is waiting to be switched on and off.
