What is the power adapter?

Power adapter is a power supply conversion device for small portable electronic equipment and electronic appliances. It is generally composed of shells, transformers, inductors, capacitors, control ICs, PCB boards and other components. Its working principle is converted from AC input to DC Output; can be divided into wall type and desktop type according to the connection mode. It is widely used in security cameras, set-top boxes, routers, LED light, massage devices and other equipments.

But when it comes to the power adapter, many people may not know what it is. But the rectangular accessory on the laptop charger or the mobile phone charger is common for us, yes, that is the power adapter, which is a small power supply conversion devices. They are mostly used on portable electronic devices or electronic appliances, like game consoles, walkmans, laptops, and mobile phones. Its role is to convert the high voltage of 220V or 110V at home into a stable low voltage of about 5 volts to 20 volts that these electronic products, to make they work normally. What is the power adapter will be popularized in the following explanation:

In fact, the function of the power adapter is the role of voltage transformation, that is, the high AC voltage, will be transformed the voltage through the rectification of the power adapter, and then, into low-voltage DC power. Such as input: 100-240VAC 50-60HZ : 12VDC 1A This is the conversion of high voltage 100-240V into low voltage 12V. Generally speaking, there is a label on the product. The power, output input voltage and current amount are marked below. Special attention should be paid to the output voltage category. This is called "Browsing power adapter". In the country of 100V, this feature will be more effective. 

Power adapter is a power supply conversion device for small portable electronic equipment and electronic appliances. It is generally composed of shells, transformers, inductors, capacitors, control ICs, PCB boards and other components. Its working principle is converted from AC input to DC Output; can be divided into wall type and desktop type according to the connection mode. It is widely used in security cameras, set-top boxes, routers, LED light, massage devices and other equipments.

Let me show you what should be paid attention to on the label of the power adapter:

1. Model: of the adapter, for example, the model of this adapter is SOY024A-1200200CN, it tells us a few information, that is, its manufacturer, wattage, etc., the beginning of SOY is ## company code generally, 1200200 is to explain this adapter 12V2A, 24W, CN means pins.
2. The INPUT of the adapter is generally 100-240V ~ 50-60Hz in China, which shows that this adapter can work normally under the voltage of 100V-240V; the third is the OUTPUT of the adapter, These 2 numerical values can quickly calculate the wattage of this adapter, for example, this adapter, voltage 5V * current 2A = 10W (power), indicating that this power supply is a 10W adapter.
3. There is a label on the power adapter, which is marked with indicators such as power, input and output voltage and current, especially pay attention to the input voltage range.
