Description
AC adapter 12v 5a for most of the early power adapters used linear transformers. With the requirements of high efficiency and wide input voltage range for power adapters in consumer electronic products, and the increase of copper, iron and labor costs, most of the original linear transformers in this kind of power adapters were gradually replaced by switching power supplies.

How the adapter could used in which applications?
Power adapters are widely used in daily life, such as refrigerators, washing machines, air purifiers and so on. In addition to these, there are things we often come into contact with, such as universal 9v ac adapter LED lamps and ac to dc converter 6v lighting equipment at home, ac dc adapter 9v 1.5 a for digital cameras, landline phones, routers, laptops and so on.
Part of materials for 250V ac to 12v dc converter
The transformer is made of silicon steel sheet. After the transformer is powered on, magnetic flux will be generated. The magnetic flux will cause the force between silicon steel sheets to produce buzzing sound, which is normal. But the earth sound is abnormal for many reasons: 1. The AC voltage is unstable. 2. The chip is broken. 3. Turn to turn short circuit. 4. The element is damaged.
