Before the module power supply leaves the factory, there are often rigorous tests, and high and low temperature tests are among them. The module power supply that has passed the high and low temperature test can ensure the quality of the product, so that the customer can reduce the probability of occurrence and increase the use period in the whole process of application. Although the module power supply that just went out in the production line can be applied immediately, many of the time the product was found in the hands of the customer. This is because of the simple plug-in detection during the processing, and there is no long-term plug-in detection of the natural environment.
Most of the common faults in module power supplies are generated in the early and middle stages, and manufacturers can't properly manipulate the mid to late stages, so only the early stages of manipulation. Before handing the goods to the customer, the problem is erased before delivery.
The key methods of the embrittlement of the module power supply are the constant warm temperate load embrittlement and the high temperature plugging high and low temperature test. The common one is high temperature embrittlement. According to the high-temperature embrittlement, the defects or quality of the commodity components can be exposed, thereby improving the reliability and credibility of the product.
The high-temperature embrittlement of the module power supply refers to the high-temperature application of the simulated environment, and the high and low temperature test time is usually specified as 12-48 hours. There are two kinds of high temperature embrittlement steps, which are set in a high temperature natural environment and plugged in and embrittled. This is a high-impact natural environment with a more extreme natural environmental standard impact module power supply.
The role of module power high and low temperature test:
1. When the railway power supply is embrittled, the monitor is applied on the application computer, and the statistical data of the power supply under the working attitude can be seen, showing the application state of the power supply.
2, long-term embrittlement, can monitor the changes in module characteristics caused by temperature changes.
3. In the case of embrittlement, the problems that occur in the processing of the power supply can be checked.
4. In the case of embrittlement, the module can operate smoothly for a long time and promote the credibility of the product.
Usually in the whole process of high and low temperature test, the state of power application is more extreme than the natural environment that people usually use, and the specification is more stringent. Only such detection can show the credibility of the module power supply, and the module power supply manufacturer guarantees the product quality.
