Cooling fans are commonly used cooling devices in our daily life. They can be seen everywhere in various electronic products. Here are the test methods for turning on the cooling fans:
1. Starting voltage: the voltage that can start the operation of the DC fan after turning on the switch "ON"
2. Locking current: The fan that can lock the machine, the locking current is measured in fresh air for 3 minutes
3. Noise standard: The noise standard test refers to the DIN45635 standard, the measurement is carried out in a soundproof room, and the microphone is placed one meter away from the DC fan
4. Speed: The speed is measured after 3 minutes of continuous rotation
5. Current: The current is measured after 3 minutes of continuous rotation
6. Input power: The input power is measured after continuous rotation for 3 minutes.
