目前单个电源模块几平很难通过SURGE、EFT、CE、RE等EMC实验，尽管国外的产品寿命长、可靠性高、EMI控制很好，但是其抗干扰性的性能仍不够强。开关电源大多数是通过UL及3C认证的，EMI性能是有保证的，但是模块化后不通过是因为测试EMI的方法，想要让设备通过EMC测试还需做好外围电路设计

先择申源模块最好是选择功率在所用的30 -80%为宜，一般这个功率范用内其各项性能发挥稳定可靠。等级分类主要有商用级、工业级和军用级，不同的等级对工作温度、震动、湿度等要求不同。为了保证产品长期稳定可靠的工作，因此在选择产足时，要考虑实际应用环境。

At present, a single power module is difficult to pass SURGE, EFT, CE, RE and other EMC experiments, although foreign products have long life, high reliability, and good EMI control, but their anti-interference performance is still not strong enough. Most of the switching power supply is through UL and 3C certification, EMI performance is guaranteed, but the modularization is not passed because of the test EMI method, want to let the equipment through the EMC test also need to do a good peripheral circuit design

The preferred source module is best to choose the power in the used 30-80% is appropriate, generally this power model within its performance is stable and reliable. There are mainly commercial grade, industrial grade and military grade, and different grades have different requirements for working temperature, vibration, humidity and so on. In order to ensure the long-term stable and reliable work of the product, it is necessary to consider the actual application environment when choosing full production.
