THE NEW ENERGY STAR VERSION 2.0 SPECIFICATION FOR EXTERNAL POWER SUPPLIES - ENERGY STAR Powered by an ENERGY STAR® qualified adapter for a better environment WHAT IT MEANS FOR CONSUMER ELECTRONICS MANUFACTURERS In April 2008, the new ENERGY STAR Version 2.0 external power supply (EPS) specification was finalized and will become effective on November 1, 2008. To help makers of consumer electronics products better understand Version 2.0, this fact sheet: ¦ Provides an overview of the various energy efficiency standards for EPSs. ¦ Describes the benefits of specifying EPSs that comply with the Version 2.0 specification for your consumer electronics product. ¦ Gives instructions on how to comply with the Version 2.0 specification and join the ENERGY STAR program. Overview of the Various EPS Specifications1 There are currently three different EPS specifications - California Energy Commission (CEC) Standards (required in California), EPA ENERGY STAR Specification (voluntary) and the federal standard (required nationwide). Their effective dates are described below. ¦ ENERGY STAR Version 1.1 EPS specification and the CEC Tier i EPS standard, which have identical efficiency requirements, are both currently in effect. ¦ CEC Tier II EPS standard and the federal standard2 for EPSs, which have identical efficiency requirements and are more stringent than ENERGY STAR Version 1.1, will go into effect on July 1, 2008. ¦ ENERGY STAR Version 2.0 EPS specification (more stringent than the new CEC Tier II and the federal standard) will go into effect on November 1, 2008,3 Compared to Version 1.1, the ENERGY STAR Version 2.0 EPS specification includes: ¦ More stringent active mode efficiency levels for low-voltage EPSs4 and standard EPSs. ¦ More stringent no-load efficiency levels for AC/DC and AC/AC EPSs ¦ Requirement that EPSs with greater than or equal to 100 watts input power must have a power factor of 0.9 or greater at 100% load when tested at 115 V. 1 See tables in Attachment 1 fully describing the CEC, ENERGY STAR, and federal criteria and see Attachment 2 for examples of efficiency levels that must be met for typical EPSs. 2 As defined in the Energy Security and Independence Act of 2007 and part of the DOE appliance standards. Please contact Victor.petrolati@ee.doe.qov for more information.

A low voltage model is an EPS with a nameplate output voltage of less than 6 volts and a nameplate output current greater than or equal to 550 milliamps (0.55 amperes). ------- Benefits of Specifying ENERGY STAR Qualified EPSs for Your Consumer Electronics Products and Joining ENERGY STAR ¦ Be an Environmental Leader. EPA can help promote your ENERGY STAR efforts to further enhance your company's reputation as an environmental leader. By specifying ENERGY STAR qualified Version 2.0 EPSs, your products use the most efficient EPSs available, more efficient than federal or California standards. ¦ Increase Sales by Promoting an Important Product Feature: Energy-Efficiency. Display the ENERGY STAR graphic for products using ENERGY STAR qualified EPSs. The ENERGY STAR mark is recognized as the symbol for energy efficiency around the world. Although the savings for a single product using a Version 2.0 qualified EPS are small, the collective savings for a product line can be enormous. For example, cell phone companies that have employed ENERGY STAR qualified EPSs have saved their customers millions of dollars in energy costs. ¦ Benefit from Ongoing ENERGY STAR Consumer Education Campaigns. The ENERGY STAR program works hard to raise awareness about the benefits of labeled products. EPA-sponsored public service announcements and public relations campaigns result in millions of dollars in ad equivalency and hundreds of millions of media impressions annually. ¦ Comply with Federal Purchasing Guidelines and Standards and International Criteria. Federal buyers are directed by Energy Policy Act of 2006 to purchase ENERGY STAR qualified products. Products using ENERGY STAR Version 2.0 qualified EPSs comply with mandatory federal and California standards (effective July 2008) and criteria in Australia, European Union, and China. How to Retain Your ENERGY STAR Partner Status as a Maker of Consumer Electronics Products Using Qualified EPSs By November 1, 2008, products must use EPSs that meet Version 2.0 standards. To retain your ENERGY STAR Partner Status: 1) Update your product specifications to include EPSs meeting ENERGY STAR Version 2.0. Your supplier should not have difficulty finding EPSs that comply with Version 2.0. In fact, in EPA's specification development dataset, close to 70% of EPS makers had at least one model meeting the active and no-load requirements. 2) Test your products' EPSs - or ask your supplier to do so. Contact Robert Huang (contact info below) if you require assistance with EPS testing. 3) Re-submit your products to EPA ENERGY STAR.
