    Tips: Is a switching power supply AC or DC?

    Commonly used switching power supplies generally have an AC input and a DC output. There are many kinds of output direct current and voltage. There is no difference between the DC and AC switches in essence, they all have the same function to control the disconnection and connection of the power input line. In actual use, the AC switch is generally installed on the positive circuit at the front end of the electrical appliance, while the AC switch is installed on the live wire line at the front end of the electrical appliance.

    The difference between the two can only be defined by definition. Usually, the input voltage of the AC switching power supply is AC. The input voltage of the DC switching power supply is DC, and the AC power supply is also equal to ac/dc, and the DC power supply is equal to dc/dc, but sometimes dc/ac is also called DC power supply.
