Final EPS Specification with Notes
Below is the product specification for ENERGY STAR qualified single voltage external ac-dc and ac-ac power supplies. A product must meet all of the identified criteria if it is to be qualified as
A product must meet all of the identified criteria if it is to be qualified as ENERGY STAR by its external power supply manufacturer. 1) Definitions: The goal of this ENERGY STAR external power supply specification is to recognize those models with an efficient ac-dc or ac-ac conversion process.
Please note, however, that use of an ENERGY STAR qualified external power supply will not automatically or solely ensure compliance with the Executive Order, as it is based on the standby power consumption of the product system (the power supply and all other components). 2.
External power supplies are often referred to as “adapters” and/or “chargers” in marketing literature and trade publications. EPA's ac-dc and ac-ac definitions are intended to cover many of these adapters and chargers, except where explicitly excluded on page 2 of these Eligibility Criteria.
Therefore, if Power Supply 1 in Table 2 had an actual average efficiency of 30%, it would satisfy the Active Mode requirement because it surpassed the ENERGY STAR minimum average efficiency of 25%. 2 (a) “Ln” refers to the natural logarithm.
