UPS: Documents

• Description: Final PIER-CEC report (2005)
• Description: The purpose of this document is to provide instructions to manufacturers of data center UPS systems on how to measure and report the efficiency of their UPS systems under different linear and nonlinear loading conditions. This guideline was created to facilitate the collection of data from UPS manufacturers as part of their "Routine tests," "Type tests," or "Factory witness tests/on-site tests." It is based on procedures described in IEC 62040-3, Uninterruptible power systems (UPS) - Part 3: Method of specifying the performance and test requirements. This IEC standard has also been adopted by the National Electrical Manufacturers Association (NEMA) as part of NEMA Standards Publication PE-1 2003, Uninterruptible Power Systems (UPS) - Specification and Performance Verification.
• Description: The purpose of this document is to provide instructions/guidelines for reporting the efficiency of UPS systems that are installed in data centers. Data collected from this project will be shared with the UPS industry including manufacturers such that they can compare actual field data with technical specification data (if any). The data collected will also be used to help specify UPS efficiency on UPS nameplates such that end users can be informed about UPS efficiency.
• Description: The Swiss Federal Office of Energy (SFOE) commissioned a project for developing a basis for comparing UPS system efficiency . The result of this project was a labeling criteria and a Quality/Efficiency (Q/E) Matrix for UPS systems. This proposed method could be the foundation of a European Code of Conduct (COC) activity on UPS starting from November of 2004. As part of our UPS project we are interested in harmonizing any proposed US labeling criteria with the Swiss Energy Office labeling criteria and is soliciting comments on this proposed method from UPS manufacturers and interested parties.
