The high temperature embrittlement of module power supply refers to the natural environment of high temperature application of simulated commodities. The high and low temperature test time is usually 12-48 hours. There are two steps of high temperature embrittlement, which are set in high temperature natural environment and plug-in embrittlement. This is in high temperature natural environment, with the more extreme natural environment standard impact module power supply.
Most common faults of module power supply products are in the early and middle period, and the manufacturers can not accurately control the middle and late periods, so only in the early stage of operation. Before handing over the goods to the customer, wipe out the problems ahead of time before delivery. The key to the embrittlement of module power supply is the load embrittlement of the constant temperature zone and the high temperature plug in test at high temperature and low temperature. According to the high temperature embrittlement, the defects or quality of commodity components can be exposed, and the reliability and credibility of the commodity are improved.
Function of high and low temperature test of module power supply:
1. in the brittle process, the module can operate smoothly for a long time, and improve the credibility of the commodity.
2. when the power module is embrittlement, monitor is carried out on the application computer, which can see the statistical data of power supply in working attitude, which reflects the application status of power supply.
3. for long-term embrittlement, the module characteristics can be monitored for changes caused by temperature change.
4. during embrittlement, the problems of power supply in the process of processing can be checked.
