    Abstract Based on UPS system configuration specifications for various electronic information system rooms，this paper states configuration requirements，operation mode and equipment utilization rate for“N”system，“N + X”system and“2 N / M（N + 1）”system. By calculating and analyzing availability indicators of several differently configured UPS systems and their single and dual bus UPS power supply system，it also discusses the design principle and attentions for UPS system configuration，demonstrated by an example for UPS system configuration design.
