Oops! 110/24v.
Connected bench power supply and the current shows 1 amp, so anything over 30w should be fine. Smallest available seems to be 60w and input ranging from 110-240v.

Or, indeed, would anyone have the Denford spec for this?

The above has failed. Only details I can see is the manufacturer Lambda, now TDK-Lambda I think. It is clearly just a 200v/24v switching power supply, but should I be looking for anything in particular amp wise. According to the wiring diagram it only supplies the ESR circuit. In the meantime, any r...

Great!
Thank you.

I am considering buying one of these two machines and wonder if the electrical specification sheets are still available? I have attached photos of the data plates. I am wondering why the full load current is much higher on one than the other. Also, are the electrical wiring diagrams available? Thank...
