Description

Technical Field

[0001] This utility model relates to a testing instrument, and more particularly to an instrument that can comprehensively and accurately evaluate and test the output parameters of a DC power supply. Background Technology

[0002] With the widespread application of electronic devices, reliable DC power supplies are crucial for ensuring their stable operation. In high-power DC power supply systems, large load fluctuations generate high-frequency interference signals in the DC power grid, such as ripple voltage, surge voltage, spike pulse voltage, and startup disturbance voltage. The high peak values ​​of these interference signals can affect the normal operation of electrical equipment. Traditional DC power supply testing relies heavily on manual operation and multiple independent testing tools, which is not only inefficient but also makes it difficult to obtain a comprehensive quality assessment. Therefore, developing an integrated and automated DC power supply quality testing instrument is essential. Utility Model Content
