CSA C865.1:25

Description

Preface 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. 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
