  The power adapter is also called an external power supply. It is a power supply voltage conversion device for small portable electronic equipment and electronic appliances. It is commonly found in small electronic products such as mobile phones, liquid crystal displays, and tablet computers. Its function is to convert the high voltage of 220 volts at home into a stable low voltage of about 5 volts to 24 volts that these electronic products can work, so that the electronic devices can work normally.

What issues need to be considered when choosing a power adapter(图1)

  The power adapter plays a vital role in the safe and reliable operation of electronic equipment. Therefore, the power adapter should be selected in the system development stage of the electronic equipment, rather than when the entire system design is about to be completed, otherwise it will often delay the development time of the system and increase the cost of the system. The following describes the considerations for selecting a power adapter:

  1. The appearance, size, and power plug specifications of the country where the power adapter is used.

  2. The specifications of the DC connector mating with the equipment.

  3. Determine the required output voltage and current according to the power consumption of the electronic equipment.

  4. Whether safety certification and safety standards are required.
