标准摘要
[中文适用范围]： 本文件 a) 规定了安全特低电压 (SELV) 和限制功率电源 (LPS) 应用的支持，这些应用通过以下方式提供远程供电： - 符合 ISO/IEC 11801 系列标准参考实现的 4 对平衡布线，每导体电流不超过 500 mA； - 使用每导体电流不超过 1000 mA 的 1 对平衡布线； 并针对通过平衡布线为终端设备提供远程供电的应用。 b) 覆盖了支持平衡布线远程供电所需的传输和电气参数。 c) 包括不同安装场景及其对平衡布线支持远程供电能力的影响。 d) 规定了 ISO/IEC 11801-1 中规定的布线的设计和配置。 [外文原描述]： ISO/IEC TS 29125:2017+A1:2020 This document specifies the use of generic balanced cabling for customer premises, as specified in the ISO/IEC 11801 series, for remote powering of terminal equipment. It provides guidance on new cabling installations and renovations. The customer premises may encompass one of more buildings or may be within a building that contains more than one organization. The cabling may be installed prior to the selection of remote powering equipment or powered terminal equipment. This consolidated version consists of the first edition (2017) and its amendment 1 (2020). Therefore, no need to order amendment in addition to this publication. The content of the corrigendum 1 (2025-12) has been included in this copy.
