What is the power AC & DC Adapter?
Power adapter is a power supply conversion equipment for small portable electronic equipment and electronic appliances. It is generally composed of shell, transformer, inductance, capacitor, control IC, PCB board and other components. Its working principle is to convert AC input into DC output. According to the connection mode, it can be divided into wall type and desktop type. It is widely used in security camera, set-top box, router, light bar, massage instrument and other equipment.
Instructions for power adapter,AC to DC Adapters:
There are several items that need attention on the label of the power adapter (hereinafter referred to as adapter). First, the model of the adapter. For example, the model of the adapter is xve-120100, which tells us several information, such as its manufacturer and main parameters. The beginning of xve is generally the company code, 120100 means that the adapter is 12V1A, and 050200 means 5v2a. The second is the input of the adapter, which is generally AC100-240V ~ 50-60Hz in China, which shows that the adapter can work normally under the AC voltage of 100v-240v. The third is the output of the adapter. DC 12V = 1a, which represents DC with rated voltage of 12V and maximum current of 1a. Two numbers can quickly calculate the wattage of the adapter. For example, the voltage of the adapter is 12V * the 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 AC (50 / 60Hz). Basically, most laptops have an external power supply and are connected to the host with a power cord, which can reduce the volume and weight of the host. Only a few models have a built-in power supply in the host.
There is a nameplate on the power adapter, which indicates the indicators such as power, input and output voltage and current. Pay special attention to the range of input voltage. This is the so-called "travel power adapter". This feature is very useful if you go to a country where the mains voltage is only 110V. Some parallel laptops are sold only in the country of origin, Without this compatible voltage design, even a single input voltage of 110V will burn out if it is inserted under the 220V mains voltage in China.
Purpose of power adapter
