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,适用于 50 Hz 或 60 Hz 时高达 250 V 的直流电源或高达 1000 V 的交流电源,并且额定输出电压 ≤ 50 V rms,频率为与 IEC 60357 中规定的卤钨灯和其他白炽灯相关的电源频率偏差或导体之间或任何导体与地之间 ≤50 V 不平滑直流。注:50 V 额定输出电压的限制符合 IEC 60449 的 I 级要求。具有过热保护装置的电子降压转换器的特殊要求在附录 C 中给出。固定式独立 SELV 转换器的特殊要求,它是附件 I 中给出了装置中的接线。 IEC 61047 涵盖了性能要求。插入式转换器是灯具的一部分,与内置转换器一样,也包含在灯具标准的附加要求中。 [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 first edition of IEC 61347-2-2, together with IEC 61347-1, cancels and replaces the second edition of IEC 61046, published in 1993, and constitutes a minor revision. This standard shall be used in conjunction with IEC 61347-1. It was established on the basis of the first edition (2000) of that edition.
