Eaton: Which UPS is right for the job? (part 2)

  • Middle East: Wednesday, September 16 - 2009 at 12:44

Traditionally, data centre managers and facilities managers could choose from three UPS topologies: standby, line-interactive and double-conversion - offering widely varying levels of efficiency, performance and protection. The latest generation of double-conversion UPSs offers unique multi-mode capabilities. The UPS operates in a very high-efficiency mode unless power conditions warrant a switch to the higher protective level typical of double-conversion mode.

This Eaton white paper describes how various UPS topologies work and looks at the impact of operating mode on five key factors of UPS performance.
