Abstract
A power supply is for receiving an AC voltage and outputting a DC voltage and an output current to an electronic device. The power supply includes an input module, an output module, a measuring interface, a measuring interface, and a switch module. The input module is for receiving the AC voltage. The output module is for outputting the DC voltage and the output current to the electronic device. The measuring interface is for electrically contacting with a part of the electronic device. The measuring module is for measuring the DC voltage, the output current, and a voltage and a current of the part of the electronic device. The switch module is for choosing one of the output module and the measuring interface to be electrically connected to the measuring module.
