A power adapter is a power supply device that can supply power according to the needs of electronic products. What is the difference between the power adapter and the power supply, the two are not the same, the following YHY will give you a detailed introduction, so what is the use of the power adapter, its main role is to believe that the power supply, now the equipment, can be said to be completely inseparable from the power adapter, I believe you have deep experience of the mobile phone out of power days, next, Just talk about what is the difference between the power adapter and the power supply. I hope YHY finishing of the small series can help you.
What's the difference between a power adapter and a power supply?
An adapter, specifically, an adapter for any device. For example: mobile phone power adapter, shaver adapter and so on. In short, it's a device. Power, on the other hand, means something different. A power supply, by definition, is the source of electricity. There are AC power sources, such as our common household power supply, to the larger picture, the national grid. There are DC power sources, such as dry batteries, batteries. The power adapter is generally used to boost or step-down voltage, to charge mobile phones or other devices, and the power supply is a fixed voltage rating capacity.
What is the use of a power adapter?
Simply put, the role of the power adapter is the role of voltage change, that is, the high voltage of the visual AC is converted into low voltage DC electricity through the rectifier and voltage change of the power adapter. For example, the input is 100-240VAC and the output is 50-60HZ. 12VDC 1A This converts a high voltage of 100-240V to a low voltage of 12V. Generally speaking, there is a nameplate on the power adapter, marked below the power output input voltage and flow targets, in particular to pay attention to the output voltage category, this is the so-called "tour power adapter", if the mains voltage as long as 100V country, this feature is very effective, some imported products note this computer is only sold in the country of origin, There is no such plan, and even as long as a single output voltage of 100V, when it is plugged in, the 220V electric voltage of our country will be abandoned.
What is a power adapter
First, the power adapter is a small portable electronic equipment and electrical and electronic power supply conversion equipment, generally by the shell, transformer, inductor, capacitor, control IC, PCB board and other components, its working principle from AC input to DC output; According to the connection mode can be divided into wall type and desktop type. Widely used in security camera, set-top box, router, light bar, massage instrument and other equipment.
Two, the power adapter is also called external power supply, is a small portable electronic equipment and electronic electrical power supply voltage conversion equipment, commonly seen in mobile phones, liquid crystal display and laptop and other small electronic products.
