United States DOE EPS Level VI

Effective February 21, 2016, external power supplies (EPS) used to convert household electric current into direct current or lower-voltage alternating current to operate consumer products, including lighting, will be required to comply with the Energy Conservation Standards for External Power Supplies (EPS). The law establishing these rules can be found here. The test procedure for this can be found here.

These requirements are applicable to all Class A external power supplies. A Class A EPS is a device that:

  1. is designed to convert line voltage AC input into lower voltage AC or DC output;
  2. is able to convert to only 1 AC or DC output voltage at a time;
  3. is sold with, or intended to be used with, a separate end-use product that constitutes the primary load;
  4. is contained in a separate physical enclosure from the end-use product;
  5. is connected to the end-use product via a removable or hard-wired male/female electrical connection, cable, cord, or other wiring; and
  6. has nameplate output power that is less than or equal to 250 watts.
  7. Power of ethernet (POE) injectors and midspans are required to comply, reference page 41 of DOE Frequently asked questions.

On December 30, 2017, The U.S Department of Energy (DOE) has published the final guidance pertaining to External Power Supplies definitions and scope of coverage. This final document represents the definitive view of the agency on the questions addressed and may be relied upon by the regulated industry and members of the public. It states:

DOE will not consider a power supply with any one of the following characteristics to meet the definition of an “external power supply” under EPCA, so long as the power supply is not, in fact, distributed in commerce for use with a consumer product:

  1. a power supply requiring 3-phase input power, which is incapable of operating on household current;
  2. a DC-DC only power supply, which is incapable of operating on household current;
  3. a power supply with a fixed, non-removable connection to an end-use device that is not a consumer product ;
  4. a power supply whose output connector is uniquely shaped to fit only an end-use device that is not a consumer product;
  5. a power supply that cannot be readily connected to an end-use device that is a consumer product without significant modification or customization of the power supply itself or the end-use device;
  6. a power supply packaged with an end-use device that is not a consumer product, as evidenced by either: a. such device being certified as, or declared to be in conformance with, a specific standard6 applicable only to non-consumer products; or b. such device being excluded or exempted from inclusion within, or conformance with, a law, regulation, or broadly-accepted industry standard where such exclusion or exemption applies only to non-consumer products; or
  7. a power supply distributed in commerce for use with an end-use device where:
    1. the end-use device is not a consumer product, as evidenced by either the circumstances in (6)(a) or (6)(b) above; and
    2. the end-use device for which the power supply is distributed in commerce is reasonably disclosed to the public, such as by identification of the end-use device on the packaging for the power supply, documentation physically present with the power supply, or on the manufacturer’s or private labeler’s public website; or
  8. a power supply that is not marketed for residential or consumer use, and that is clearly marked (or, alternatively, the packaging of the individual power supply, the shipping container of multiple such power supplies, or associated documentation physically present with the power supply when distributed in commerce is clearly marked) “FOR USE WITH COMMERCIAL OR INDUSTRIAL EQUIPMENT ONLY” or “NOT FOR RESIDENTIAL OR CONSUMER USE,” 7 with the marking designed and applied so that the marking will be visible and legible during customary conditions for the item on which the marking is placed

GlobTek offers a large range of DOE EPS Level VI compliant power supplies, mostly globally certified to ITE 60950-1, Limited Power Source, ICT 62368-1, Medical 60601-1, Household Use UL1310 and 60335-1, and more.
