FROM REDUNDANT SOURCES TO DUAL INDEPENDENT SOURCES-An innovative power architecture providing high availability and power quality for mission-critical applications

摘要

Power quality and availability are primary considerations in the design of technical infrastructures for mission-critical computer systems. Large internet data centers, enterprise networks, telecommunications centers, banks and hospitals all require clean, dependable power to ensure round the clock operation, 7 days a week, 365 days a year, without stopping even for maintenance. In conventional computer centers, power protection was relatively straight forward, usually based on a centralized UPS. However today's new needs require different UPS and low voltage distribution solutions, including new architectures to maintain a high level of availability throughout all phases of operation and maintenance on complex sites (computer maintenance, modifications to cabling system and computer rooms, electrical maintenance from the high-voltage end down to the final distribution system). The article presents the conditions for high availability and a number of solutions that use the latest technology to optimize cost, footprint and availability.
