I purchased an QJE switching mode DC regulated power supply. Unbenosed to me, it was a 220V PS rather than 110V. Is there any step-up adapters Im can buy?
The 220V cord has 3 flat pins. The top one is verticle and the 2 bottom one are slanted inwards at the bottom.
A- Which model is it? Some are switchable with a 110/220 V selector on the rear panel (some models it is on the bottom).
B- Is the power cord plugged into the rear of the unit using an IEC connector similar to what a PC power supply uses? You can simply substitute a North American grounded cord and switch the input to 110V.
There is a noise offset control that can be adjusted to eliminate pulse noise from the power supply. Ripple is less than 100 mVpp at load. Input is 110 or 220 V AC, switch selectable from the rear panel.

M/N is PS30SWVIII. The selector switch is on the bottom. I just ordered the power cord you mentioned. If this works, you saved me over 100 smackers! I can't thank you enough!

Hope it works out OK for you. There's a few variations of that socket that the main cord plugs into on the back of the unit. I hope the one they send is the right one. I have dozens of those things around from all the old computers and audio equipment I've scrapped over the years.
A little screw driver should be able to flip that input selector to 110 for you. I suppose to be in complete compliance you should change the fuse to an 8 amp from a 5 amp but I don't think it's really that necessary. Keep some 8 amp fuses around if it ever decides to blow.
Let us know how you make out.

220 is two 110 wires with a ground. There isn't a neutral wire. The wires don't care what color they are, but you do
