I have searched and can not find any published specs for the universal fader wing power supply. I am also having trouble finding anyone selling them. The spec sheet for the fader wing only says that a 12 Volt power supply is included and does not give a part number. I'd love to know the barrel size and the thread size of the locking ring. I'd love to get an additional power supply because I move my wings around and I'd like to leave a power supply in each spot. I'd also prefer to get a power supply with a cord instead of a wall wart, so I'd love to find a matching aftermarket power supply with a cord and the appropriate barrel and locking nut, if that exists. One thing I don't like about a lot of the power supplies you get these days is that they have 5 different plugs for various countries, i don't want that added connection, I just one that is not bulky, with an integral US plug.
We have an optional power supply that does work with the Universal Wings that use a standard IEC input cord. While it does use IEC cords we also offer locking IEC cords. The ETC part numbers you would want to consider are PSU - PS450 and Locking IEC Cord US - W6579. These part number should be available through most standard ETC outlets.
Thanks Matt, so it's the same PS as a colorsource console, it appears. It does appear to be a 5.5X2.1mm barrel connection from what I can tell.
