scope:

This document provides the methodology to be used by vendors and third party independent laboratories in the formation of telecommunications energy efficiency ratios (TEER) for various typical operating modes of Uninterruptible Power Supply/System (UPS) systems. The requirements and definitions in this document are for UPS systems that are deployed in the information and communications technology (ICT) industry. This supplemental standard represents one part of the larger ATIS suite of standards concerning Telecommunications Energy Efficiency (ATIS-0600015.xx). This supplemental standard (ATIS-0600015.12) specifically addresses uninterruptible power supplies and is to be used in conjunction with ATIS-0600015.

Purpose

This document provides a set of definitions, requirements, and guidelines for calculating the TEER of UPS products. The test methodology employed to verify the energy consumption, used as part of the TEER calculations, is specific to power equipment and therefore differs a bit from ATIS-0600015, but also draws from it. 

Application

This document (and supporting documentation) is intended to be used by communication network operators, equipment manufacturers, suppliers, and test laboratories as a standard method for determining the energy consumption of UPS systems. By comparing the TEER reports of various products, a communications network operator can select equipment that meets their energy consumption targets for the operating mode in which they plan to deploy/use their UPS system.
