    No,ETC does not ring a bell.

    I worked for a small place in southern NH called "New Hampshire Transformer", which closed up in 1999 when the owner died rather unexpectedly. I also worked for a short time for the precursor to RMS up in Dunbarton.

    Al, Could've sworn they were Merrimack Magnetics but unpacked a few and they were made by ETC. I don't recall where ETC is from, do you? They may have been sourced by several companies as they were made to print.

    Sell as is.
    They are ideal for the simple Allegro chips and the L something, something, something series of chip that need about 30 volts to run safely.

    If they are doing a full 4 axis machine they could use two, one for X and Y and one for Z and A

    Funnily enough I recently bought 12 of these off Ebay Uk for the same purpose

    What combination of CNC transformers to offer?

    I have several hundred high quality transformers with 110/220 primaries and 20v ct @ 5A RMS secondaries. My plan is to have one of the kids sell these things on Ebay either 2 or 3 to a box, using the "all you can fit" boxes with suitable protection, of course

    I realize the voltage is low but are these worth cascading in series for CNC use for 28-ish, 56-ish, 72-ish after rectification? How many should we offer in a pack to make it worth while. We're thinking maybe 2/$20 plus shipping so maybe 3/$25.
