IEC 60598-2-23:20 20规定了ELV光源的超低压照明系统的要求，用于电源电压不超过1 000 V的普通室内使用。并联连接的灯具通过自由悬挂的连续支撑导体或轮廓供电，系统的ELV部分中的电流不超过25A。 这第二版取消并取代了1996年出版的第一版和修正案1:20 00。本版构成技术修订版。 与上一版相比，本版包括以下技术变更（无重大技术变更，见附录A）: a)标题已被修改以允许包括其他光源； b)范围已更新，以与IEC 60598的其他部分保持一致-2系列并包括其他光源； c)规范性参考文献以及变压器和控制设备标准的参考文献已更新； d)删除短路试验（23.7.6.1和23.7.6.2），现在参考第1部分中的相同试验。

IEC 60598-2-23:2020 specifies requirements for extra-low-voltage lighting systems for ELV light sources, intended for ordinary interior use on supply voltages not exceeding 1 000 V. The luminaires, being connected in parallel, are supplied via freely suspended continuous supporting conductors or profiles, the current in the ELV part of the system not exceeding 25 A.
This second edition cancels and replaces the first edition published in 1996 and Amendment 1:2000. This edition constitutes a technical revision.
This edition includes the following technical changes with respect to the previous edition (there are no major technical changes, see Annex A):
a) The title has been modified to allow the inclusion of other light sources;
b) The scope has been updated to be aligned with the other parts of the IEC 60598-2 series and to include other light sources;
c) Normative references and the reference to transformer and controlgear standards have been updated;
d) The short circuit test (23.7.6.1 and 23.7.6.2) was removed and reference is now made to the same test in Part 1.
