Multi-Mode UPS Units Can Boost Efficiency
August 25th, 2010 By: Kevin Normandeau
Power cost can be as much as 30% of data centers operating cost. In the quest to reduce energy consumption and cooling costs, data center managers have been looking more closely at every system. This new white paper from Eaton reports that legacy uninterruptible power systems (UPSes) could be squandering as much as 10 percent of incoming energy in the course of doing their jobs. Since most of the power lost by a UPS is dissipated as heat, an inefficient UPS costs more in cooling as well.
New, groundbreaking UPS units maximize efficiency by operating in multiple modes, changing their operating characteristics to adapt to the electrical conditions of the moment. By engaging internal components only as necessary, these multi¬mode UPSes can achieve exceptional efficiency—up to 99 percent across a very broad load range.
However, multi¬mode UPSes from different manufacturers vary considerably in how they work, the level of protection they can offer, and their true efficiency under real-world load levels. This white paper looks at five questions you need to ask before selecting a high-efficiency, multi¬mode UPS for your data center.
A simple change in your power system can pay for itself many times over— and return thousands of dollars to your IT budget. To read this white paper and learn more click here.
