Hulford CSA, Project Toronto, Ontario Manager C22.2 No. 107.1-01 Canadian Standards Association x September 2001 Preface This is the third edition of CSA Standard C22.2 No. 107.1, General Use Power Supplies. It

36、is one of a series of Standards issued by the Canadian Standards Association under Part II of the Canadian Electrical Code. It supersedes the previous editions published in 1995 and 1991. This edition incorporates the requirements for solar photovoltaic (PV) technology, DC charge controllers, utilit

37、y-interconnected inverters, and electric vehicle (EV) charging systems. This Standard was prepared by the Subcommittee on C22.2 No. 107.1 under the jurisdiction of the Technical Committee on Industrial Products and the Strategic Resource Group, and has been formally approved by the Technical Committ

38、ee. Interpretations: The Strategic Resource Group has provided the following direction for the interpretation of standards under its jurisdiction: “The literal text shall be used in judging compliance of products with the safety requirements of this Standard. When the literal text cannot be applied

39、to the product, such as for new materials or construction, and when a relevant committee interpretation has not already been published, CSAs procedures for interpretation shall be followed to determine the intended safety principle.” September 2001 Notes: (1) Use of the singular does not exclude the

40、 plural (and vice versa) when the sense allows. (2) Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability for their particular purpose. (3) This publication w

41、as developed by consensus, which is defined by CSA Policy governing standardization Code of good practice for standardization as “substantial agreement. Consensus implies much more than a simple majority, but not necessarily unanimity”. It is consistent with this definition that a member may be incl

42、uded in the Technical Committee list and yet not be in full agreement with all clauses of this publication. (4) CSA Standards are subject to periodic review, and suggestions for their improvement will be referred to the appropriate committee. (5) All enquiries regarding this Standard, including requ

43、ests for interpretation, should be addressed to Canadian Standards Association, 178 Rexdale Boulevard, Toronto, Ontario, Canada M9W 1R3. Requests for interpretation should (a) define the problem, making reference to the specific clause, and, where appropriate, include an illustrative sketch; (b) pro

44、vide an explanation of circumstances surrounding the actual field condition; and (c) be phrased where possible to permit a specific “yes” or “no” answer. Committee interpretations are processed in accordance with the CSA Directives and guidelines governing standardization and are published in CSAs p

Canadian Standards Association General Use Power Supplies September 2001 xi Foreword The Canadian Standards Association (CSA) develops standards under the name Canadian Standards A

46、ssociation, and provides certification and testing under the name CSA International. CSA International provides certification services for manufacturers who, under license from CSA, wish to use the appropriate registered CSA Marks on certain products of their manufacture to indicate conformity with

47、CSA Standards. CSA Certification for a number of products is provided in the interest of maintaining agreed-upon standards of quality, performance, interchangeability and/or safety, as appropriate. Where applicable, certification may form the basis for acceptance by inspection authorities responsibl

48、e for enforcement of regulations. Where feasible, programs will be developed for additional products for which certification is desired by producers, consumers, or other interests. In performing its functions in accordance with its objectives, CSA does not assume or undertake to discharge any respon

49、sibility of the manufacturer or any other party. The opinions and findings of the Association represent its professional judgement given with due consideration to the necessary limitations of practical operation and state of the art at the time the Standard is processed.
