IEC1000—4—11为一欧洲标准,规范用来验证电子/电器产品在电源电压骤降、短时中断或电压变化时抗干扰能力的测试。这个标准虽然来自欧洲,却已被世界各地的生产厂家在测试中所广泛采用。 标准设立的需要是显而易见的。而上述抗干扰能力的测试,有很多种不同方法,所以为了规定一个统一标准,把测试规范化是必须的。无论怎样。IEC 1000—4—11标准在某些方面仍然存在着随意性,例如它没有绝对地说明哪种测试应该针对哪一类型的产品。 此标准尝试着去说明不同交流电源的参数要求适合某些特定测试。可是,这些要求往往超出测试所需。举个例子,涌入(IN—RUSH)电流功能明显超出了被测产品的需要,而且降低了测试本身的经济效益。
IEC1000-4-11 is a European standard that is used to test the immunity of electronic / electrical products against power surges, short interruptions or voltage changes. Although this standard from Europe, but has been around the world manufacturers in the test widely used. The need to establish a standard is obvious. The above anti-interference ability test, there are many different ways, so in order to provide a unified standard, the test standardization is necessary. no matter what. The IEC 1000-4-11 standard is still arbitrary in some respects, for example it does not absolutely state which test should target which type of product. This standard attempts to demonstrate that different AC power supply parameters are suitable for some specific tests. However, these requirements often exceed the test requirements. For example, the IN-RUSH current function clearly exceeds the needs of the product under test and reduces the economics of the test itself.
