- Why does the power adapter make noise? How does this noise occur? What is the cause of the noise?
Why does the power adapter emit noise? How is this noise generated? What is the cause of the noise? The following Shenzhen Unicom power adapter manufacturers will explain it to you.
When AC 220V is transformed by a transformer and converted to DC through a rectifier, there is consumption here, and these consumptions are converted into heat, so it is normal for the power adapter to heat up. The transformer is made of silicon steel sheet. When the transformer is energized, a magnetic flux is generated. The magnetic flux will cause a force between the silicon steel sheets to generate a click sound, but this is normal. However, the sound of too much fire is not normal, and the power adapter makes a lot of noise, as follows:
1. Short circuit between turns.
2. Component damage.
3. The AC voltage is unstable.
4, the chip is damaged.
All of these are the reasons why the power adapter makes noise. If you want to know more exciting content, please continue to pay attention to Shenzhen Lianyunda official website!
