Problems solved by technology
At present, the instruments for testing LED driving power supply on the market include general-purpose AC power supplies, power meters, digital multimeters, etc. These test instruments are usually suitable for small-batch product inspections, and the test operation process is cumbersome and labor-intensive. The test system is of great significance for improving the test efficiency of LED drive power supply, improving product quality, simplifying the operation process and improving production efficiency. At present, there is no such AC power supply test system in the domestic counterparts, and there are no technical articles on this aspect in the literature. to report
