    Product Details

    • Preface/Scope
    • Items Included

    Preface


    This is the second edition of CSA C381.1, Energy performance of external ac-dc and ac-ac power supplies. It supersedes the previous edition published in 2008 under the title, Test method for calculating the energy efficiency of single-voltage external ac-dc and ac-ac power supplies.


    This Standard specifies requirements, definitions, and test methods for measuring the energy performance of external ac-dc and ac-ac power supplies.


    The Harmonization Committee intended that this Standard would harmonize with Appendix Z to Subpart B, Part 430 of Title 10 to the United States Code of Federal Regulations, entitled “Uniform Test Method for Measuring the Energy Consumption of External Power Supplies”.


    CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of Natural Resources Canada (NRCan), BC Hydro, Hydro-Québec, and the Ontario Ministry of Energy.


    This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.


    This Standard was prepared by the Harmonization Committee on the Performance of External Power Supplies and Battery Charging Systems, under the jurisdiction of the Technical Committee on Residential Equipment and the Strategic Steering Committee on Performance, Energy Efficiency, and Renewables, and has been formally approved by the Technical Committee.


    This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.


    Scope


    1.1 General


    This Standard specifies a test method for calculating the energy performance of external power supplies (EPS) across a full range of load conditions. It covers single-voltage and multiple-voltage external ac-dc and ac-ac power supplies.


    Note: External power supplies are designed to convert line voltage ac into the low-voltage output (ac or dc) typically required by laptop computers, cordless and cellular phones, portable stereos, etc. EPS are contained in a separate housing from the product they are powering.


    1.2 Purpose


    The test method specified in this Standard is intended to complement the methodology contained in CSA C381.2. This Standard and CSA C381.2 define two classifications of products for the purpose of energy-efficiency testing; products within the scope of CSA C381.2 are not intended to be tested by this Standard. Annex B provides information on determining the appropriate test method (this Standard or CSA C381.2) for measuring a product’s energy efficiency.


    1.3 Exclusions


    The following are not covered by this Standard:


    a) Dc-dc voltage conversion equipment, such as dc-dc converters, are not included in this Standard, except to the extent that such circuitry is found within a power supply.


    b) A medical device as defined in Section 1 of the Canadian Medical Devices Regulations.


    c) A direct operation, ac-dc external power supply with nameplate output voltage less than 3 V and nameplate output current greater than or equal to 1,000 mA that charges the battery of a product that is fully or primarily motor operated are not covered by this Standard.


    d) Indirect operation non-Class A external power supplies.


    Note: These products may be covered by CSA C381.2.


    1.4 Terminology


    In this Standard, shall is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; should is used to express a recommendation or that which is advised but not required; and may is used to express an option or that which is permissible within the limits of the Standard.


    Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.


    Notes to tables and figures are considered part of the table or figure and may be written as requirements.


    Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
