CSA C865.1:23

Scope This standard describes the procedures to be followed and the precautions to be taken in measuring performance of LED drivers commonly used in general lighting, exterior lighting, and 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)
