In the quest to reduce energy consumption and cooling costs, data center managers have been looking more closely than ever at the energy efficiency of their uninterruptible power systems (UPSs). Legacy UPSs—those five to 10 years old—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 UPSs 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 multimode UPSs can achieve exceptional efficiency—up to 99 percent across a very broad load range. However, multimode UPSs 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, multimode UPS for your data center.
