Power adapter is also called external power supply. It is a small portable electronic equipment and power supply voltage conversion equipment of electronic appliances. Inloom technology simply popularizes the function and application of power adapter.
Generally speaking, the function of power adapter is transformer and rectifier. Household AC is 220V, while our equipment land is DC. Therefore, it is certain that the power adapter is a transformer and rectifier. The transformer is made of silicon steel sheet. After the transformer is powered on, magnetic flux will be generated, which will lead to the force action between silicon steel sheets, resulting in buzzing sound, which is normal. Many: AC voltage instability, chip damage, short circuit, component damage, etc. Therefore, the function of power adapter is to convert alternating current into direct current.
In our daily life, power adapters can be seen everywhere. For example, power adapter is widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instruments and meters, medical equipment, semiconductor refrigeration and heating, air purifier, electronic refrigerator, liquid crystal display, LED lamps, audio-visual products, security, computer chassis, digital products and instruments.
