Uninterruptible Power Supplies Specification Version 2.0
The ENERGY STAR specification for uninterruptible power supplies is currently under revision. Materials related to this revision process are provided below. Stakeholders who received past communications related to development of Version 2.0 will continue to receive updates on the development effort. To be added to the contact list, stakeholders are encouraged to contact firstname.lastname@example.org with their contact information to be added to the list.
EPA and DOE have included minor clarifications into the ENERGY STAR test method for UPSs. These clarifications have been carried over from a Version 1.0 guidance document and cover issues such as UPSs that operate with both 3-phase and single-phase power, UPSs that have additional DC-output voltages, and a longer measurement period. There were no changes to the specification. The original guidance document and updated program requirements are posted below.
