This recently introduced step-dimming module product line has been expanded with additional options for dimming control of LED luminaires. SD series devices work with two standard wall switches to allow multi-level step-dimming of LED luminaires. Two models provide three levels of light output. The SD3-25 offers 25/50/100 output. The SD3-33 offers 33/66/100 output. Also available is the SD2 bi-level module, which offers 50/100 output. The modules work with occupancy sensors and operate in conjunction with any 0-10V dimmable LED driver. Intended for indoor use, the step-dimming modules feature 100-277Vac universal voltage input and low insertion loss.
