AC adapter, AC means alternating current, and AC adapter is the alternating current power supply. Many electrical appliances require an AC adapter. In the industrial field, we call it switching power supply, but it is a little different in appearance.
AC adapter means alternating current. Alternating current changes the direction of current flow at regular time intervals. The AC adapter is used to convert the voltage of the external AC power to the rated voltage required for the operation of the IT equipment to meet the power requirements of the equipment. When using an AC adapter, you should know the input voltage range of the power adapter, preferably a universal AC100-240V voltage input.
For the sake of safety, when choosing an AC adapter, be sure to choose a product produced by a regular manufacturer.
