In order to improve the testing method of the electrical performance of the mine-used DC stabilized power supply, this paper designed a test device for the electrical performance of the mine-used DC stabilized power supply based on STM32F407VET6 single chip microcomputer. The device is mainly composed of AC power output, DC power input, analog load, operation control and other units. It can achieve AC0∼1254V AC voltage output underground and the output voltage deviation value, source effect, load effect, and overload of the mine DC stabilized power supply. The current protection value and short-circuit current value are tested and displayed on the display of the industrial computer.
