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,并且额定输出电压小于或等于至 50 V rms,频率偏离电源频率@或与 IEC 60357 中指定的卤钨灯和其他白炽灯相关的导体之间以及任何导体与接地之间的 120 V 无纹波直流电。注:50 V 额定输出电压的限制符合 IEC 60449 的 I 级。附件 C 中给出了具有过热保护装置的电子降压转换器的特殊要求。提供安全超低电压(以下SELV)@在附件I中给出。性能要求由IEC 61047涵盖。作为灯具@一部分的插入式转换器@与内置转换器一样由灯具标准的附加要求涵盖。 [外文原描述]: IEC 61347-2-2:2011 specifies particular safety requirements for electronic step-down convertors for use on d.c. supplies of up to 250 V or a.c. supplies of up to 1 000 V, at 50 Hz or 60 Hz and with rated output voltage 50 V r.m.s. at a frequency deviating from the supply frequency, or 120 V ripple free d.c. between conductors and between any conductor and earth, associated with tungsten-halogen lamps as specified in IEC 60357 and other filament lamps. This second edition of IEC 61347-2-2 replaces the first edition (2000), Amendment 1 (2005) and Amendment 2 (2006). The major modification for this second edition is the changeover from SELV equivalent to SELV. This publication is to be read in conjunction with IEC 61347-1:2007 .
