Power adapter (Power adapter),in laptop adapter shop also known as an external power supply (switching power supply adapter), it is a small, portable electronic devices and electrical and electronic power supply voltage conversion device, it was the result of in real life, electronic devices are often not directly use household power, because the home, using a 220 volt power supply voltage, while the the universal electronic products generally required supply voltage is about 5 volts to 20 volts. Therefore, the role of the power adapter is crucial (module power). With it, we can facilitate the safe use of these electronic products. Power adapter, what is it? For this problem, Xiaobian collected data be simply summarized.

Composition and application of the power adapter (power adapter works)
The power adapter is common in mobile phones, LCD monitors and notebook computers and other small electronic products.The laptop battery adapter shop .Usually casing, power transformer and rectifier circuit, their output type can be divided into the type of AC output and DC output type; connection can be divided into the wall plug and the desktop. Widely used in the phone Cordless phone, game consoles, language repeater, walkman, notebook computers, cell phones and other devices.

Computer power adapter
The Toshiba PA3716E-1AC3 power adapter is widely used in industrial automation and control, military equipment, scientific equipment, LED lighting, industrial equipment, communications equipment, electrical equipment, instrumentation, medical equipment, semiconductor cooling and heating, air purifiers, electronic refrigerator, LCD monitors, LED lighting, communication equipment, audio-visual products, security, computer chassis, digital products and instruments such as the field, and have a negligible role in these areas. Power adapter What?

The role of the power adapter
In general,Toshiba PA3905U-1BRS Battery the power adapter to the role of transformer and rectifier.For example Acer TravelMate 5720 Adapter ,Household AC 220v, and our computer land is DC 12v (as if), and so can be sure that the power adapter is a transformer Chief rectifier. The adapter is a transformer, then we should know, through the transformer transformer AC 220v DC rectifier, here are consumed, which consumed is converted into heat, power adapter fever normal. The transformer is a silicon steel sheet made of, the transformer is energized, magnetic flux is generated, the magnetic flux will incur generated between the force acts in the silicon steel, thereby generating a buzzing sound, which is normal. Burned earth, the sound is not normal, why are many: 1, AC voltage instability. 2, chips breakage. 3, inter-turn short circuit. 4 component damage. By the way, the role of the adapter is to convert alternating current into direct current electronic products.

HP 417220-001Power adapter space are generally built-in, general adapter volume is not small, the small volume of the machine are external, in order to save space, and to replace is also convenient, mains adapter with high voltage, put the inside of the machine is more dangerous.

The power adapter should pay attention to several issues

The label above the power adapter (below adapter) will generally have several needs attention.
First, is the model of the adapter, such as the the Fengyun adapter model is XVE-120100,Battery For HP Probook 4530S it tells us several manufacturers, wattage the XVE beginning, generally is XX code, 120100 is to explain this The adapter is 12W 050200 is 10W.

Second, is the adapter INPUT (input), in general, China is generally 100-240V 50-60Hz,like the Fengyun adapter can work in 100V-240V voltage below normal.

Third, the adapter OUTPUT (Output), two figures can be calculated very quickly of this adapter wattage, such as the Toshiba PA3715E-1AC3 adapter voltage 12V * current 1A = 12W (power), this power is 12W adapter.

Most laptop power adapter suitable for 100 ~ 240V AC (50/60Hz). Basically most laptop regard the external power supply, a power cord and a host connection, which would reduce the size and weight of the host, and only a handful of models to power the built-in host.

Power adapter has a nameplate above marked power, input and output voltage and current indicators, with particular attention to the range of the input voltage, which is the so-called "travel power adapter", if the mains voltage only a 110V country,HP Probook 4510S Laptop Battery this feature is useful when some parallel laptops are only sold at the origin, this compatible voltage design, or even only a single input voltage of 110V, 220V mains voltage plug will burn.

The role of the power adapter is the home of the high voltage into low voltage, stable work so that they can work properly. Instead it will bring a lot of inconvenience to our day-to-day use. This paper describes the role, composition and application of the power adapter as well as attention to some problems when using the power adapter.
