This seems counter-intuitive and has always puzzled me. A "normal" power supply converts AC to DC, so an "inverted" power supply converts DC to AC? That's what I always guessed...

I suppose that happens occasionally, but in practice they are made with protective circuitry. I loaned out my EU-2000 to my father who promptly connected it to a shorted out cord. (Much to my consternation, because I had heard that same story) All that happened was the thing stopped putting out power until reset and restarted. Then all was well. Vaughn

Sorry, I'm not finding that, either on the page labeled 21 or on pdf page 21. Any help?? Mike |
