Why should the module power supply be tested for aging

existModule powerBefore leaving the factory, there are often rigorous inspections, and high and low temperature tests are among them. The modular power supply that has undergone high and low temperature tests can ensure the quality of the product, allowing customers to reduce the probability of abnormality during the entire application process and increase the service life. Although the module power supply that just went out of the production line can be used immediately, many of the products are in the hands of customers before they find that they are not available. This is due to the simple plug-in detection during the processing, and the long-term plug-in detection in a different natural environment is not done.

Most of the common failures of modular power products occur in the early and mid-to-late stages, and manufacturers cannot accurately manipulate the mid-to-late stages, so only the early stages of operation. Before the product is handed over to the customer, the problem should be eliminated before delivery.

The key to the embrittlement method of the module power supply is the normal temperature temperate load embrittlement and the high temperature plug-in high and low temperature test. The common one is high temperature embrittlement. According to the high temperature embrittlement, the shortcomings or poor quality of commercial components can be exposed, thereby improving the reliability and credibility of the products.

The high-temperature embrittlement of the module power supply refers to the natural environment of high-temperature applications of simulated products. The high and low temperature test time is usually specified as 12-48 hours. There are two high-temperature embrittlement steps, one is set in a high-temperature natural environment, plug-in embrittlement. This is a high-temperature natural environment, using a more extreme natural environment standard impact module power supply.

The function of the module power supply high and low temperature test:

1,existPower moduleWhen embrittlement is carried out, the monitor can be used on the computer to see the statistical data of the power supply under the working attitude, which reflects the application status of the power supply.

2, Long-term embrittlement, can monitor the change of module characteristics caused by temperature change.

3, When embrittlement, it can check out the problems of the power supply in the process of processing.

4When it becomes brittle, the module can operate smoothly for a long time, which improves the credibility of the product.

Usually in the whole process of high and low temperature test, the conditions of power application are more extreme than the natural environment that people usually use, and the specifications are more stringent. Only such a test can reflect the credibility of the module power supply, and it is the module power supply manufacturer that guarantees the product quality.
