The manufacturer of led power supply 24v tells you what the power adapter does. Generally speaking, the role of the power adapter is the transformer and rectifier. Household AC is 220v, and our computer is usually DC 12v, so it is certain that the power adapter is a transformer and rectifier. The led power supply 24v manufacturer tells you that the adapter is a transformer, so we should all know that AC 220v is transformed into a transformer through a transformer and transformed into a direct current through a rectifier. There is consumption here, and these consumption will be converted into heat, so the power adapter will generate heat. normal.

The led power supply 24v manufacturer tells you that the transformer is made of silicon steel sheets. After the transformer is energized, magnetic flux is generated. The magnetic flux will cause the silicon steel sheets to generate force and generate a buzzing sound. This is normal. However, the sound of the ground is abnormal due to many reasons: 1. The AC voltage is unstable. 2. The chip is damaged. 3. Short circuit between turns. 4. The components are damaged and so on. By the way, the role of the adapter is an electronic product that converts alternating current into direct current.
The manufacturer of led power supply 24v tells you that the power adapter with large space is generally built-in. Generally, the size of the adapter is not small, and the small-sized machine is external. In order to save space, the manufacturer of led power supply 24v tells you to replace it. Convenient, the mains voltage used by the adapter is relatively high, and it is dangerous to put it inside the machine.
