Data Centers – A Global Perspective

  • Wasted energy burdens the environment and increases operational expenses
    • Carbon Footprint in IT Computing
      • Only 3% of the energy entering a data center is used for net computing creating opportunities for effiency improvements (Source: IBM, 2009)

  • Two complementary Eaton-proprietary technologies to maximize UPS performance & efficiency
    • Variable Module Management System (VMMS)
      • Maximized efficiency in double conversion mode
        • Both in single- and multi-UPS systems applications
    • Energy Saver Systems (ESS)
      • The ultimate savings: 99% efficiency
      • Automatic fast transfer to double conversion mode when needed (in less than 2 ms)

Variable Module Management System (VMMS)

The Challenge For UPS’s

FACTS

  • In double conversion mode, the efficiency of any UPS varies depending on the % of load
    • Highest efficiency when close to full capacity
  • UPS systems rarely loaded at full capacity
    • This is fact in redundant systems

CHALLENGE

  • How to maximize efficiency potential of UPS systems with lighter loads

img-advtech6The Solution: Eaton VMMS

  • How to maximize efficiency with lighter loads in double conversion mode 
    • Especially in multi-UPS and redundant system configurations
  • Solution #1 (+)
    • Concentrate load on certain UPS’s to maximize UPS load level and overall system efficiency
      • Some energy savings
        • Limited to multiple-UPS systems (with several UPS in parallel)
        • Still not optimal
  • Solution #2 (+++)
    • Eaton 9395 and its Variable Module Management System 
      • Automatically optimize efficiency at UPM level
        • Concentrate the load on certain UPM’s to maximize overall system efficiency
      • Only possible thanks to modularity of Eaton 9395 UPS
        • Not limited to multiple-UPS systems
        • Achieve even higher optimization thanks to UPM’s modularity

VMMS Principle

  • Example With Same Load Applied To Different Multi-UPS Configurations
  • img-advtech7VMMS maximizes % load of each UPM
    • Optimizing overall system efficiency

Energy Saver System (ESS)

checklist-2 Efficient
99% efficiency across entire operating range

img-advtech9

checklist-2 Intelligent
Detects incoming power quality and engages modules as needed in < 2ms
checklist-2 Reliable
Proven Eaton technology ensures reliability and continuous load availability

Energy Saver System (ESS) allows the UPS user to achieve the ultimate power efficiency without compromising the protection of the supported equipment.


Energy Saver System saves even more at lower loadings

Maximum Efficiency Tracking

img-advtech10

 

  • ESS Efficiency - 99%across the complete operating range
  • 85% reduction in lossescompared to legacy transformer-based UPS
  • Continuous power tracking and proprietary DSP algorithms combined with transformer free design topology ensures critical loads are always protected
