GiantPCTechnology-The role and precautions of the power adapter

GiantPCTechnology Power Adapter Manufacturer: GiantPCTechnology Power Adapter Manufacturer Power adapter, switching power supply (Poweradapter), also known as external power supply (switching power adapter), is a power supply voltage conversion device for small portable electronic equipment and electronic appliances. It is not possible to use household electricity directly, because the power supply voltage used at home is 220 volts, and the power supply voltage required by common electronic products is generally about 5 volts to 20 volts. Therefore, the role of the power adapter and switching power supply is crucial (module power supply). With it, we can use these electronic products conveniently and safely. So, what is the role of the power adapter and switching power supply?

Composition And Application Of Power Adapter And Switching Power Supply (Working Principle Of Power Adapter And Switching Power Supply): Power adapters are commonly found on small electronic products such as cell phones, LCD monitors, and notebook computers. It is generally composed of a casing, a power transformer and a rectifier circuit. According to its output type, it can be divided into AC output type and DC output type; according to the connection method, it can be divided into wall type and desktop type. It is widely used in Walkman, notebook computer, cellular phone and other equipment. computer power adapter

Computer Power Adapter: Power adapters are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instrumentation, medical equipment, semiconductor refrigeration and heating, air purifiers, electronic refrigerators, liquid crystal displays, LED lamps and lanterns , communication equipment, audio-visual products, security, computer cases, digital products and instruments and other fields, and have a role that cannot be ignored in these fields. So what are the functions of the power adapter?

The role of the power adapter: Generally speaking, the role of the power adapter is a transformer and a rectifier. Household AC is 220v, and our computer ground is DC 12v, so we can be sure that the power adapter is a transformer and rectifier. The adapter is a transformer, the AC 220v is transformed through the transformer, and the DC is transformed through the rectifier. There is consumption here, and this consumption will be converted into heat, so it is normal for the power adapter to heat up. The transformer is made of silicon steel sheets. After the transformer is energized, a magnetic flux is generated, and the magnetic flux will cause a force between the silicon steel sheets, resulting in a humming sound, which is normal. But the sound of the earth is not normal if it is too hot. There are many reasons: 1. The AC voltage is unstable. 2. The chip is damaged. 3. Short circuit between turns. 4. Component damage, etc. The function of the adapter is to convert the alternating current into the direct current of the electronic product.

Power adapters with large space are generally built-in. Generally, the adapters are not small. Small-sized machines are external. In order to save space, it is also convenient to replace them. The mains power used by the adapter is relatively high. Dangerous inside Points to note when using the power adapter

There are generally several items that need to be paid attention to on the label of the power adapter (hereinafter referred to as the adapter).

First, it is the model of the adapter. For example, the model of this adapter is GT-120109. It tells us several information, that is, its manufacturer, wattage, etc. The beginning of GT is generally ##company code, and 120109 means this. The adapter is 12W, and the 050209 is 10W;

The second is the INPUT (input) of the adapter, which is generally 100-240V~50-60Hz in China, which means that the adapter can work normally under the voltage of 100V-240V;

The third is the OUTPUT (output) of the adapter. Two numbers can quickly calculate the wattage of the adapter. For example, in this adapter, the voltage is 12V*current 1A=12W (power), indicating that the power supply is a 12W adapter.

Most notebook computer power adapters can be used for 100 ~ 240V AC (50/60Hz). Basically, most laptops have an external power supply and use a power cord to connect with the host, which can reduce the size and weight of the host. Only a few models have the power supply built into the host.

There is a nameplate on the power adapter, which indicates the power, input and output voltage and current, etc., 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 This feature is very useful. Some parallel notebook computers are only sold in the country of origin. There is no such compatible voltage design, and even only a single input voltage of 110V. If you plug it in under the 220V mains voltage in my country, it will burn out.

Summarize

The function of the power adapter is to convert the high voltage in the home into a stable low voltage that can work, so that they can work normally. Without it, it will bring a lot of inconvenience to our daily use. This article mainly introduces the function, composition and application of the power adapter, as well as some issues that need to be paid attention to when using the power adapter.

The above is the introduction of GiantPCTechnology to related issues.
