The power supply of the selectable input power supply of the present invention can accept an AC or DC input power source and process it to convert to the DC voltage and current required to comply with the consumer. Since the AC and DC power sources cannot be input at the same time, the power input selection means 22 is used to select the type of power source to be input so as to prevent the parent and DC power sources from being simultaneously input. The power input selection means 22 can be implemented as a slide cover as shown in the first figure, and an appropriate circuit block can be used to distinguish the type of power input. If the input power is AC power, it will be input to the AC to DC converter 24, and the AC to DC converter 24 can convert the AC power to DC power, and then output the DC power to the voltage adjusting device 26 for voltage regulation or The processing of the downgrade.
