  The power adapter is a power supply conversion device for small portable electronic equipment and electronic appliances. It externally connects the power supply to the host with a line, which can reduce the size and weight of the host. Only a few devices and electrical appliances have built-in power in the host. Inside. laptop power adapter

  The adjustment range of the input voltage of the power adapter is the maximum change value of the allowable input mains voltage, generally 90~264V AC, corresponding to 90V~132V AC under 110V voltage, and 176V~264V AC under 220V voltage..

  The application of the power adapter in the notebook computer, the semiconductor integrated circuit (IC) used in the notebook computer needs DC voltage. The DC voltage is used because the IC cannot work under the AC voltage of 50Hz or 60Hz, and the IC will be reverse voltage (reverse bias voltage) )damage. Generally, the fault voltage of IC is below DC20V (DC5V~10V), and IC can work stably only within the voltage range of high-power power adapter specified in the product specification, so the voltage of the power adapter that supplies power to the IC must be within the working range. laptop power adapter

  Input voltage range: It is the variation range of the mains voltage allowed by the power adapter, and it is also the mains voltage range that ensures the normal power supply of the power adapter. The larger the range, the better the adaptability. The input voltage range should be AC 100 ~ 240V, special reminder: it It is divided into two working states under AC 110V and AC 220V voltage environment. The correct test method is to switch the voltage test when the power adapter stops working.
