CSA C865.1:25

Foreword This foreword is not part of ANSI C82.16-2025. This is a revision of ANSI C82.16-2023. Suggestions for improvement of this standard will be welcomed. They should be sent to: National Electrical Manufacturers Association 1812 North Moore Street, Suite 2200 Arlington, VA 22209 www.makeitelectric.org This standard was developed and approved for submittal to ANSI by the C82 Consensus Body. Approval of this standard is not meant to imply that all committee members voted to approve it. Note: The user’s attention is called to the possibility that compliance with this standard could require use of an invention covered by patent rights. By publication of this standard, no position is taken with respect to the validity of any such claim(s) or of any patent rights in connection therewith. If a patent holder has filed a statement of willingness to grant a license under these rights on reasonable and non-discriminatory terms and conditions to applicants desiring to obtain such a license, then details may be obtained from the Secretary. This is the second edition of CSA C865.1, Light-emitting diode drivers — Methods of measurement . It supersedes the previous edition published in 2023. CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of BC Hydro, Efficiency Manitoba, Natural Resources Canada, and Hydro Quebec. This standard is considered suitable for use for conformity assessment within the stated scope of the standard. This standard was reviewed by the CSA Subcommittee on Methods of Performance Measurement of LED Drivers, under the jurisdiction of the CSA Technical Committee on Performance of Lighting Equipment and the CSA Strategic Steering Committee on Performance, Energy Efficiency, and Renewables, and has been formally approved by the CSA Technical Committee. This standard has been developed in compliance with the Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. 1.1 General 1.2 Purpose This standard complements other standards and specifications that set performance limits, such as ANSI C82.18, CSA865.2 and ANSI C137.4, and provides testing methods. 1.3 Scope This standard describes the procedures to be followed and the precautions to be taken in measuring the performance of LED drivers commonly used in general lighting, exterior lighting, roadway lighting, and similar applications. The scope includes LED drivers that may have these characteristics: a. Input supply voltage up to 600 VDC or 600 VAC (60 or 50/60 Hz) b. Output open-circuit voltage of 600 V or less c. Constant-current or constant-voltage direct current (DC) output d. Fixed, pulse-width modulation (PWM), or programmable (tunable or dimmable) output power e. External (standalone) or internal (enclosed in luminaire) f. References
