The expanding role of uninterruptible power systems in telecommunications

The author addresses the expanding role of uninterruptible power systems (UPS) in today's telecommunications operations. He discusses the advantages and disadvantages of application, technology approach, reliability, service, efficiency and intelligence features. A perspective is given to the needs and technology of the present and those of the future. UPS configurations are examined, and attention is given to sizing considerations, battery issues, energy management, and site and cost considerations. It is concluded that the economics and rationale for justifying a UPS depend on a number of variables. The UPS offers the power engineer the opportunity to build reliable, cost-effective, and efficient power supplies while contending with economic and manpower constraints.<
