标准摘要
[中文适用范围]： IEC 61347 的这一部分规定了电子降压转换器的特殊安全要求，用于在 50 Hz 或 60 Hz 时高达 250 V 的直流电源或高达 1 000 V 的交流电源以及额定输出电压 50 V rms（频率偏离电源频率或导体之间或任何导体与地之间的 50 V 不平滑直流电，与 IEC 60357 中指定的卤钨灯和其他白炽灯相关。该合并版本由第一版（2000 年）、修正案 1（2005 年）和修正案 2（2006 年）组成。因此，除了本出版物之外，无需订购修订。 [外文原描述]： This part of IEC 61347 specifies particular safety requirements for electronic step-down convertors for use on d.c. supplies up to 250 V or a.c. supplies up to 1 000 V at 50 Hz or 60 Hz and rated output voltage 50 V r.m.s. at a frequency deviating from the supply frequency or 50 V unsmoothed d.c. between conductors or between any conductor and earth, associated with tungsten-halogen lamps as specified in IEC 60357 and other filament lamps. This consolidated version consists of the first edition (2000), its amendment 1 (2005) and its amendment 2 (2006). Therefore, no need to order amendments in addition to this publication.
