Response topic	Conducted EMI for Nemesis
Message	Several typical input conducted EMI for Nemesis series of Flyback converters are shown at: http://www.SMPS.com/Design/Nemesis/Nemesis_EMI_vB7.shtml http://www.SMPS.com/Design/Nemesis/Nemesis_EMI_vB1.shtml No output noise measurements were made, as the primary application is Solid State Lighting where the load (LED) is inside of a metal enclosure together with the PSU.
