Preface<\/strong><\/p>\n

<\/p>\n

This is the third edition of CSA C22.2 No. 223, Power supplies with extra-low-voltage Class 2 outputs,<\/em> one of a series of Standards issued by the CSA Group under Part II of the Canadian Electrical Code. It supersedes the previous editions published in 1991 and 1987.<\/p>\n

<\/p>\n

This edition also incorporates CSA Technical Information Letter (TIL) No. I-42; Interim Certification Requirements for Direct Plug-in and Cord-Connected Power Supplies with Extra-Low-Voltage Class 2 Output for Outdoor Use.<\/p>\n

<\/p>\n

For general information on Standards of the Canadian Electrical Code, Part II, see the preface of CAN\/CSA-C22.2 No. 0, General Requirements \u2014 Canadian Electrical Code, Part II.<\/p>\n

<\/p>\n

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.<\/p>\n

<\/p>\n

Scope<\/strong><\/p>\n

<\/p>\n

1.1<\/p>\n

This Standard applies to<\/p>\n

<\/p>\n

a) indoor and outdoor use Class 2 power supplies with input power of 660 W or less. These units are of both the direct plug-in and cord-connected types that utilize a step-down, isolating transformer and that may incorporate rectifiers and other components to provide an ac or dc output;<\/p>\n

<\/p>\n

b) Class 2 power supplies as in Item a) employed as battery chargers for rechargeable batteries; and<\/p>\n

<\/p>\n

Note: For convenience, the term power supply may be used throughout this Standard.<\/p>\n

<\/p>\n

c) identified Class 2 outputs or extra-low voltage outputs of products covered by other standards. For example, permanently connected units covered by CSA C22.2 No. 107.1.<\/p>\n

<\/p>\n

This Standard also provides direct plug-in requirements for products covered by other standards.<\/p>\n

<\/p>\n

1.2<\/p>\n

This Standard applies to power supplies intended for use in non-hazardous locations in accordance with the Rules of the Canadian Electrical Code, Part I, when connected to a nominal system voltage of 120 V or 240 V supply. In addition, this Standard applies to permanently connected power supplies intended for use in Class 2 lighting systems for a nominal system voltage up to 600 V.<\/p>\n

<\/p>\n

1.3<\/p>\n

These requirements do not cover the effect that a power unit may have on the equipment or system to which it is connected. A product marked for a specific end-use involving additional considerations may be subject to additional requirements found in the applicable end-product standard.<\/p>\n

<\/p>\n

1.4<\/p>\n

This Standard does not include requirements for batteries.<\/p>\n

<\/p>\n

1.5<\/p>\n

This Standard does not apply to<\/p>\n

<\/p>\n

a) nonautomotive battery chargers that do not have a Class 2 output;<\/p>\n

<\/p>\n

b) automotive battery chargers;<\/p>\n

<\/p>\n

c) transformerless, non-isolated battery chargers for charging special purpose battery packs; or<\/p>\n

<\/p>\n

d) the functional charging requirements of non-automotive battery chargers with Class 2 outputs.<\/p>\n

<\/p>\n

Note: These categories are covered by CAN\/CSA-C22.2 No. 107.2 or CAN\/CSA-E60335-2-29.<\/p>\n

<\/p>\n

1.6<\/p>\n

This Standard does not apply to products that do not have an identified Class 2 output.<\/p>\n

<\/p>\n

1.7<\/p>\n

This Standard contains requirements for the evaluation of toy transformers and power supplies in accordance with CSA C22.2 No. 173.<\/p>\n

<\/p>\n

1.8<\/p>\n

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.<\/p>\n

<\/p>\n

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.<\/p>\n

<\/p>\n

Notes to tables and figures are considered part of the table or figure and may be written as requirements.<\/p>\n

<\/p>\n

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.<\/p>\n","protected":false},"excerpt":{"rendered":"
