Principle of fan speed regulation:
The USB Fan without gear is connected directly to the fan motor by the 5V power supply of USB, while the fan with two gears has a boost circuit board inside. When it is in the second gear, the boost circuit board will raise the 5V power supply of USB and then connect to the motor, and the air volume will be large!
When using the USB Fan governor, please put the fan in the first gear, otherwise it may not be able to adjust the speed!!
Usage method:
1. First, plug the male connector of USB Fan governor into the power interface such as mobile phone charger, power bank and computer USB (ensure that the power of power interface is greater than the required power of fan or LED light), and then plug ∪ sb fan plug or USB desk lamp plug into the female connector of USB fan governor. The governor default output is on.
2. The output voltage of the left dial of the dial wheel button increases; The right dial output voltage decreases.
3. Click the dial wheel button to switch the output on or off.
4. Double click the dial wheel button to turn off the nixie tube display. Press any button to wake up the nixie tube display.
Timing time setting:
1. Long press the dial wheel button for 3 seconds to enter the timing time setting interface. "---" Represents the timing off, the display number represents the timing on.
2. In the setting interface, click the dial wheel button to switch the timing function on or off.
3. In the setting interface, press the left dial wheel key to increase the timing time and decrease the right dial timing time.
4. Long press the dial wheel button for 3 seconds to exit the timing time setting interface and start the countdown.
