Enhancing Large UPS Efficiency

As energy resources become scarce and expensive, electrical efficiency is becoming a more important performance factor in the specification and selection of large UPS systems. There are three subtle but significant factors that can materially affect a company's cost of operating a UPS system, and particularly the electrical bill. Unfortunately, the people who specify systems often fail to recognize these factors, which leads to increased costs to the owner because operational efficiencies are not correctly considered. This course addresses the common errors and misunderstandings in evaluating UPS efficiency. UPS efficiency curves are explained, compared, and their cost implications quantified. Course Credits: * This course has been approved by Institute of Electrical and Electronics Engineers (IEEE) for one (1) PDH * This course is recognized for continuing education credit from IFMA for CFM/FMP Maintenance Points. * This course has been approved by the IL Society for Professional Engineers (ISPE) for one (1) PDH
* Recognize efficiency issues involved in UPS evaluation * Interpret a UPS efficiency curve * Describe types of power loss and the total cost of inefficiency * Discuss solutions to leverage UPS efficiency including: * Technology * Topology * Modularity * Avoid mistakes that are common in UPS specification
