Using Distributed 48 V Instead of 12 V in Datacenters
Gary Edmonds, Director of System Engineering, Flex Power Modules

The measure of datacenter energy efficiency is ‘Power Usage Effectiveness’ or PUE, and the best ‘hyperscale’ installations achieve a figure of about 1.1, or 100 W lost in cooling, distribution and power conversion for every kW used by the IT equipment. As best practices trickle down to smaller datacenters, th
