  Power Adapter!EI-41 SWITCHING ADAPTOR(图1)

  Power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It is generally composed of shells, transformers, inductors, capacitors, control ICs, PCB boards and other components. Its working principle is converted from AC input to DC Output; According to the connection mode, it can be divided into wall type and desktop type. It is widely used in security cameras, set-top boxes, routers, light bars, massagers and other equipment.

  The power adapter is also called an external power supply. It is a power supply voltage conversion device for small portable electronic devices and electronic appliances. It is commonly found in small electronic products such as mobile phones, liquid crystal displays, and notebook computers.

  There are generally several items on the label of the power adapter (hereinafter referred to as adapter) that need attention. The first is the model of the adapter. For example, the model of this adapter is XVE-120100. It tells us a few pieces of information, including its manufacturer, main parameters, etc. The beginning of XVE is generally ##Company code, 120100 means this The adapter is 12W, 050200 is 10W; the second is the INPUT of the adapter, which is generally 100-240V~50-60Hz in China, which shows that the adapter can work normally under the voltage of 100V-240V; The third is the OUTPUT of the adapter. Two numbers can quickly calculate the wattage of the adapter. For example, for this adapter, voltage 12V*current 1A=12W (power), indicating that the power supply is a 12W adapter.

  The power adapter of most notebook computers can be suitable for 100~240V alternating current (50/60Hz). Basically, most notebook computers have an external power supply, and use a power cord to connect to the mainframe, which can reduce the size and weight of the mainframe. Only a few models have the power supply built in the mainframe.

  There is a nameplate on the power adapter, which indicates the power, input and output voltage and current and other indicators. Pay special attention to the range of the input voltage. This is the so-called "travel power adapter". If you go to a country where the mains voltage is only 110V When this feature is very useful, some parallel-imported laptops are only sold in the country of origin, without this compatible voltage design, or even a single input voltage of 110V, which will burn when plugged in under the 220V mains voltage in our country.
