Description / Abstract:
This standard describes the procedures to be followed and the precautions to be taken in measuring performance of LED drivers. The scope includes, but is not limited to, LED drivers with these characteristics:
• General lighting, exterior lighting, and roadway lighting applications
• Input supply voltage up to 600 VDC or 600 VAC (50 or 60 Hz)
• Output open-circuit voltage of 600 V or less
• Constant-current or constant-voltage direct current (DC) output
• Fixed, variable (dimmable), pulse-width modulation, or programmable (tunable) output power
• External (standalone) or internal (enclosed in luminaire)
PURPOSE
This document complements standards and specifications that set performance limits, such as NEMA SSL 1, and provides guidance for testing methods for government specifications and other organizations.
