医疗电源对PFC的要求？
请问医疗电源是否有对PFC有强制或者非强制的要求？有人说60W以下的医疗电源对PFC不做要求，
是否有相关的标准提到PFC的要求
标准上没看到这个说明，医疗EMC 标准为EN 60601-1-2，PFC功率因数校正与谐波息息相关，谐波需要符合EN 61000-3-2. 同意楼上 看看医疗标准为EN 60601-1-2，功率因数校正与谐波息息相关，谐波需要符合EN 61000-3-2 stey 发表于 2013-10-25 12:17 static/image/common/back.gif

6.1.3.1 Harmonic distortion
6.1.3.1.1 * Requirements
ME EQUIPMENT and ME SYSTEMS with a RATED input current up to and including 16 A per phase
and that are intended to be connected to the PUBLIC MAINS NETWORK shall comply with the
requirements of IEC 61000-3-2. If ME EQUIPMENT or an ME SYSTEM has both long-time and
momentary current ratings, the higher of the two ratings shall be used in determining the
applicability of IEC 61000-3-2. stey 发表于 2013-10-25 20:04 static/image/common/back.gif

貌似没说PF值需要限定到某值，是不是谐波过了就OK
75W以下不做要求 very good stey 发表于 2013-10-25 20:04 static/image/common/back.gif
