How to test the speed of a DC fan?
Release time:
2020-08-31
In order to understand the voltage of the DC fan,DC fan manufacturersSet an acceptable size range for the speed of the two sets of fans according to the voltage, and provide samples. After the power-on test, three results will be obtained. If the test is good, of course it is better. If the airflow of the DC fan is small or noisy, we can adjust it.
If the air volume is small, then we can slowly increase the adjustable power supply voltage, turn on the power supply of the micro fan, the speed will gradually increase, and the air volume will increase, until we confirm that the air volume of the DC fan can meet the equipment requirements and record the voltage at this time, the noise is very loud. We can use the same method to reduce the voltage of the DC fan, reduce the speed ratio, reduce the noise, and record the voltage at this time.
After testing in the above steps, provide a sample and voltage value to the DC fan supplier, record the speed at the current voltage, and then perform another sample. Basically, it doesn't matter. If these three steps still fail, we can start with step and ask the manufacturer to make another size sample. But with a sample experiment experience, the chances of success are even greater.
The above is the method of speed measurement. For more information, please consult our official website!
