The performance and working state of the switching power supply are used to measure the stability, quality and reliability of the switching power supply. The specific operation steps of the repeated on-off test are as follows:

1. The input voltage is 220v, the switching power supply has the maximum load, use the contactor to control the voltage input, close 15s, disconnect 5s, and run continuously for 2 hours to detect the working status of the switching power supply;

2. The input voltage is the overvoltage point -5v, the switching power supply has the maximum load, use the contactor to control the voltage input, close 15s, disconnect 5s, and run continuously for 2 hours to detect the working status of the switching power supply;

3. The input voltage is undervoltage point -5v, the switching power supply has the maximum load, use the contactor to control the voltage input, close 15s, disconnect 5s, and run continuously for 2 hours to detect the working status of the switching power supply.

During and after the test, if the switching power supply can work normally and the performance does not change significantly, it indicates that the switching power supply is qualified.

Because the switching power supply repeated on-off test needs to keep on and off, and the running time is long, the manual test process will be more complicated, the test time is long, and the test efficiency is low. Therefore, the repeated on-off test is suitable for testing in an automated way, which can simplify the test procedure, greatly improve the test efficiency, save the test time and reduce the test cost.


Power module automatic test system for repeated on-off test, only need to connect the tested product with the test equipment, and connected to the edge computing device ATEBOX through a communication cable, and then the test PC and ATEBOX access the same server to ensure the signal communication, then a complete test system is connected. Then you only need to drag and drop text test instructions in the system according to the manual test process to set up the test steps, and configure the voltage, load, time and other condition parameters, you can start the test.


The test speed of the power module test system is very fast, and the test results will be fed back in the form of Pass/Fail index in seconds, and whether the product is qualified is clearly visible. And the system will conduct an overall analysis of the data of the repeated switching test, quickly determine product problems, and help improve and optimize the switching power supply products.
