| 可再生能源或分布式电源与高达400伏的直流供电系统的连接 |
ITU-T L.1200系列中定义的为ICT/电信设备供电接口提供了最高400伏特DC （VDC） 供电方案，可通过新型简单直流（DC）纳米或微米电网，与可再生能源或配电源的直接使用实现很好地适配。ITU-T L.1205建议书定义了将本地或远程可再生能源统一并入高达400伏的直流供电系统，同时不降低ITU-T L.1202建议书重点为效率和可靠性规定的直流电性能。它的主要优势在于节省化石能源（主要能耗的来源）、减少温室气体（GHG） 排放并提升复原力。通过直流电网提供其它站点互连互通，甚至可带来更多的优化。与交流电（AC）相比的另一巨大优势在于，400 VDC不需要在各类输入间进行同步，从而保持了该产品架构的简洁。 |
