What Is The Role Of The Power Adapter?
Nov 26, 2018

The power adapter's role is to convert the 220 volt high voltage in the home into a stable low voltage of 5 volts to 20 volts that these electronic products can work, so that they can work normally. Without it, it will bring a lot of inconvenience to our daily use. The power adapter is also called an external power supply. It is a power supply voltage conversion device for small portable electronic devices and electronic appliances. It is commonly found in small electronic products such as mobile phones, liquid crystal displays and notebook computers.

What is the use of the power adapter? In simple terms, the function of the power adapter is to transform the voltage, that is, to convert the high voltage of the AC to the low voltage DC power through the rectification and voltage transformation of the power adapter. For example, input: 100- 240VAC 50-60HZ Output: 12VDC 1A This is the conversion of high voltage 100-240V to low voltage 12V. Generally speaking, the power adapter has a nameplate. The following points indicate the power, output voltage and current amount. Special attention should be paid to the output voltage. This is the so-called “tour power adapter”. This feature is very effective when the country is 100V. Some imported notebook computers are only sold in the country of origin. Without such a plan, even a single output voltage of 100V is inserted under the 220V mains voltage in China. Will be discarded.
