APC White Paper: A Scalable, Reconfigurable, and Efficient Data Center Power Distribution Architecture


Categories: , Tags: ,


Significant improvements in efficiency, power density, power monitoring, and reconfigurability have been achieved in data center power distribution. The past techniques of massive transformer-based power distribution units feeding under-floor hardwired circuits via rigid or flexible conduit are shown to be obsolete.
This paper explains some of the newer approaches to power distribution including modular power distribution and overhead power busway, and shows their advantages when compared to the legacy approach.
