The power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It is often used in mobile phones, liquid crystal displays and notebook computers, etc., which brings a lot of convenience to people's daily life. Consumers are best to buy the original power adapter of the product, because the original power adapter has a high degree of matching with the whole machine, and it can better play the performance of the whole machine 24V power adapter through the test of the whole machine manufacturer
The input voltage frequency is the frequency range within which the power adapter can automatically track the mains and maintain synchronization. Generally, the standard frequency of the power grid is 50Hz or 60Hz, and the power adapter allows a certain range of change in the mains frequency, which is the input voltage frequency range.
The external power adapter is more flexible to use. As long as the parameters required by the device can be met, the same adapter can be used. However, in order to ensure the normal operation of the equipment, you must choose a power adapter produced by a regular manufacturer when choosing. 24V power adapter
If the product is not tested and affixed with the CE label, the wall-mounted China-certified power adapter will be considered as a counterfeit product. All EU countries will take appropriate measures to counterfeit CE-marked products. And other products of the same manufacturer in Europe are severely punished. Therefore, if the product is tested by some illegal or crude certification body, it will be very dangerous
The power adapter is a power supply conversion device for small portable electronic equipment and electronic appliances. It is generally composed of a shell, a power transformer and a rectifier circuit. According to its input type, it can be divided into AC power adapter and DC power adapter; according to the connection method, it can be divided into wall plug Type power adapter and desktop type power adapter. It is widely used in the equipment such as telephone handsets, game consoles, language repeaters, walkmans, notebook computers, and cellular phones. 24V power adapter
Input voltage range: It is the range of the mains voltage allowed by the power adapter, and it is also the mains voltage range that guarantees the normal power supply of the power adapter. The larger the range, the better the adaptability. The input voltage range should be AC 100～240V, special reminder: it It is divided into working conditions under two voltage environments of AC 110V and AC 220V. The correct test method is to switch the voltage test when the power adapter stops working.
