Which UPS is Right For the Job?

Considerations in choosing standby, line-interactive, double-conversion UPS designs - and new high-efficiency, multi-mode capabilities - for your data center

Traditionally, data center 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:

  • Maintaining voltage within tolerances
  • Transferring among modes without locking up IT equipment
  • Transitioning gracefully to and from generator power
  • Reliability and availability
  • Energy efficiency

Data center managers now have viable and remarkably cost-effective new choices with highefficiency, double-conversion, multi-mode UPSs that combine the best of single- and double-conversion topologies: exceptional efficiency plus the high protective level of double-conversion operation.

With best practices and the right choices in equipment, data center managers can reduce energy consumption by nearly 50 percent. That means that almost three-quarters of the power utility bill will fuel actual IT processing, compared to less than 50 percent of the power supplied to a normal data center today.
