This whitepaper shows precisely how and why using high-efficiency mode UPSs can yield savings significant enough to produce a 100 percent return on investment in as little as two years. In addition, utility incentives that are commonly available can provide significant benefit. It also discusses key features to look for when evaluating high-efficiency mode UPSs and illustrates the difference between modern high efficiency mode UPSs and older model “eco mode” operations. Not all high-efficiency modes are created equal, and you have to be certain you aren’t sacrificing reliability for efficiency.
