Power and Efficiency Gains by Deploying 415V in N. American Play

Within enterprise data centers, power used for operating the facility, lighting, running IT loads and cooling is the largest operational expense. Numerous papers and articles have been published by The Green Grid, The Uptime Institute, PG&E, Lawrence Berkeley Laboratories and others discussing ways to measure, monitor and increase efficiencies. This paper discusses various approaches to reducing power consumption and to increase end-to-end efficiency in the data center by bringing 415 VAC to the cabinet level. With power densities continuing to rise, more efficient solutions continue to be explored especially as power cost increases and power availability decreases.

The power path from the building entrance to the IT loads contains several power converters and transformers for each conversion; which contribute to inefficiencies and power losses. Reducing the number of transformers and operating at a higher voltage improves efficiency and reduces electrical costs. This paper discusses an alternative approach to power distribution, presently being implemented in North American data centers that increase efficiencies and savings by reducing upfront capital costs, power consumption and floor space.
