The function of the power adapter
The power adapter is also called the external power supply (switch power adapter), it is the power supply voltage conversion device of a small portable electronic equipment and electronic appliances, this is because in real life, electronic devices are often not directly use household power, because the use of home is the power supply voltage 220 volts, and electronic products generally generally required supply voltage is 5 volts to 20 volts。 Therefore, the role of the power adapter is critical (module power)。 With it, we can use these electronic products conveniently and safely。


Constitution and application of power adapter (operation principle of power adapter)


The power adapter is common in small electronic products such as mobile phones, liquid crystal displays and notebook computers. Generally composed of shell, power transformer and rectifier circuit, according to its output type can be divided into AC output type and DC output type. According to the connection mode, it can be divided into plug wall type and desktop type. It is widely used in telephone, computer player, game player, language repeater, Walkman, notebook computer, cellular phone and so on.


Power adapter for computer


The power adapter is widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial equipment, communication equipment, electrical equipment, instrumentation, medical equipment, semiconductor refrigeration and heating, air purifier, electronic refrigerator, liquid crystal display, LED lighting, communication equipment, audio-visual products, security, computer chassis, the field of digital products and other instruments。


There is a nameplate in the power adapter, marked power, index input and output voltage and current, with particular attention to the range of input voltage, this is the so-called "Travel Adapter", if the voltage is only 110V of the state, this feature is very useful, some smuggled goods notebook computer it is only at the origin of sales, not the compatible voltage design, single input voltage or even only 110V, plug will in 220V voltage in China under fire.
