Reasons for the false standard of the DC fan current

There may be several reasons for the false standard of the DC fan current:

1. Measurement error: Some manufacturers will take into account factors such as voltage drop and measurement error when marking the current, and correct the rated current. These correction values ​​are generally small, and some manufacturers may ignore these factors, making the current identification value falsely high.

2. Circuit design problem: The circuit design in the DC fan directly affects the magnitude and change of the current. If the circuit design is unreasonable or there are some problems, the current will be falsely high or unstable.

3. Offset calibration issue: Offset calibration on the production line is also an important factor. If the production process is not perfect or the calibration method is not standardized, it is easy to cause the current identification value to be falsely high.

To sum up, there may be many reasons for the false standard of the DC fan current, and the manufacturer needs to strictly control the production and testing process to ensure the product quality and the accuracy of the label value. At the same time, consumers should also pay attention to product parameters and differences when purchasing and using DC fans, and choose products with stable quality and accurate labels as much as possible.
