Because for the current industry market, inferior power adapters account for about 30% of the market. It is a big threat to our factories that make high-quality products, because the unit price of power adapters produced with second-hand originals will be 30% or more cheaper than the unit price of our brand-new materials. As a result of the chaos in the current market, some manufacturers are struggling with prices, and quality has not received much attention. It is a big hidden danger for customers and terminal consumers. Switching power adapter
Power adapter: English name Adapter, the common power adapter on the market is a power converter that has undergone transformation, rectification and stabilization, and the output is DC, which can be understood as a low-voltage stabilized power supply when the power is satisfied. Switching power adapter
If the product is not tested and affixed with the CE label, the wall-mounted power adapter with Chinese certification 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. Switching power adapter
Since the inside of the power adapter is a switching power supply that works under high voltage and high current, the work load is relatively heavy, and it is a fully enclosed structure. There is no heat dissipation hole on the shell and no internal fan to assist heat dissipation. Therefore, the power adapter is working The internal temperature is high. In the hot summer, you can feel hot to touch the surface with your hands, and the internal temperature is even higher. Therefore, it must be properly maintained and maintained during daily office and entertainment.
