dimming results were taken at an input voltage of 120 VAC, 60 Hz line frequency, room temperature, and a nominal 36 V LED load. The output current High Limit IOUT (Max) and Low Limit IOUT (Min) were incorporated based on the USA NEMA publication SSL6-2010 section 4 page 9 for dimming performance system requirements for reference. The standard however refers to 120 VAC operating input voltage and pertains to the limits as relative light output. The limits incorporated on the succeeding graphs assumes that 100% relative light output falls on the maximum operating output current of 550 mA and 0 mA as 0% light output, and input line of 120 VAC, 60 Hz. 12.1 模拟(使用Agilent 6812B交流电源供应器)前沿调光器的调光曲线 100 NEMA Limits (Max) Output Current (0-180) Output Current (180-0) NEMA Limits (Min) 90 Relative Output Current (%) 80 70 60 50 40 30 20 10 0 0 20 40 60 80 100 Phase Angle (º) 120 140 160 180 Figure 21 – Dimming Curve at 120 VAC, 60 Hz Input.
