The power adapter is widely used in people’s daily life, due to improper use and led adapter 12v 2a.

The more problems arise due to the working principle of the led adapter 12v, etc., why does the led adapter 12v make noise? How does this noise occur? What is the cause of the noise from the led adapter 12v?

When the AC 220v is transformed through a transformer and transformed into a direct current through the rectifier, there is consumption here, and these consumption will be converted into heat, so it is normal for the led adapter 12v to generate heat. The transformer is made of silicon steel sheets. After the transformer is energized, magnetic flux is generated. The magnetic flux will cause the force between the silicon steel sheets to produce a buzzing sound, but this is normal. But the loud sound is abnormal. There are many reasons for the noise from the led adapter 12v, as follows:

* Short circuit between turns
*The component is damaged.
*The AC voltage is unstable.
* The chip is damaged.

All of the above are the reasons for the noise of the led strip lights power adapter. I want to know more about the led strip adapter, Please continue to pay attention to SMARTS for purchasing or wholesale! We will provide you with the best products and the most enthusiastic service!
