要从建筑物的市电电源为数据中心的关键负载配电，有五种主要的 UPS 系统设计配置方案可供选择。要为特定应用环境选择合适的配置方案，必须充分考虑该应用环境的可用性需求、风险承受能力、数据中心的负载类型、预算以及现有基础设施等情况。本文对这 五种配置进行了说明，并逐一论述每种方案的优缺点。随后，分析了每种配置方案的可用性，并阐述了如何选择合适的设计方案。

Some lead-acid batteries located in data centers are subject to government environmental compliance regulations. While most commercial battery back-up systems fall below required reporting levels, very large UPS and DC plant batteries may have to comply. Failure to comply can result in costly penalties. Environmental compliance regulations focus on the amount of sulfuric acid and lead in a given location. This paper offers a high level summary of the regulations and provides a list of environmental compliance information resources.

不间断电源（UPS）电池技术的选取会对保护信息技术和网络环境所用的场地要求和成本产生影响。本文将讨论电池技术对场地要求有何影响。

阀控铅酸(VRLA)蓄电池是中小型不间断电源(UPS)的首选储能电池。本白皮书探讨了技术对蓄电池整体寿命和系统可靠性的影响，此外，还将介绍VRLA蓄电池的预期性能、影响其生命周期的因素，以及故障应对机制。

This white paper explains the technical terms of power factor, crest factor, and surge factor. The use of these terms in specifying UPS is explained.

The lead-acid battery is the predominant choice for Uninterruptible Power Supply (UPS) energy storage. Over 10 million UPSs are presently installed utilizing Flooded, Valve Regulated Lead Acid (VRLA), and High Density Modular Battery Cartridges (HDBCMBC) systems. This paper discusses the advantages and disadvantages of these three battery technologies.
