CSA - C22.2 NO. 223-15

Power supplies with extra-low-voltage Class 2 outputs

inactive
Organization: CSA
Publication Date: 1 January 2015
Status: inactive
Page Count: 59
scope:

This Standard applies to

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;

b) Class 2 power supplies as in Item a) employed as battery chargers for rechargeable batteries; and Note: For convenience, the term "power supply" may be used throughout this Standard.

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.

This Standard also provides direct plug-in requirements for products covered by other standards.

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.

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.

This Standard does not include requirements for batteries.

This Standard does not apply to

a) nonautomotive battery chargers that do not have a Class 2 output;

b) automotive battery chargers;

c) transformerless, non-isolated battery chargers for charging special purpose battery packs; or

d) the functional charging requirements of non-automotive battery chargers with Class 2 outputs.

Note: These categories are covered by CAN/CSA-C22.2 No. 107.2 or CAN/CSA-E60335-2-29.

This Standard does not apply to products that do not have an identified Class 2 output.

This Standard contains requirements for the evaluation of toy transformers and power supplies in accordance with CSA C22.2 No. 173.

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.
