Alternating current and direct current power supply test board

An AC/DC power supply test bench is provided with a bench main body, a digital multimeter used for measuring DC voltage, DC current, AC voltage and AC current output by a tested device, and an oscilloscope used for measuring voltage waveform, current waveform, frequency and voltage ripple output by the tested device. The power analyzer is used for measuring the input voltage, the input current, the input frequency, the input power factor, the input power, the input end harmonic wave, the output voltage and the output current of the tested equipment, and the load assembly, the digital multimeter, the oscilloscope and the power analyzer are all assembled on the table main body. And the load assembly, the digital multimeter, the oscilloscope and the power analyzer are electrically connected with the control panel of the table main body. The alternating-current and direct-current power supply test board integrates all test equipment required by an experiment, does not need to replace the test equipment in a test
