Have a few of these from Minarik- Model RG101UC.
120 VAC input. See them on ebay:

Re: 90 volt DC motor Controllers
what did they come out of ? - just curious
Re: 90 volt DC motor Controllers
Hi dacflyer,
They came out of a thin film sputtering machine, made to move plates of metal through a processing chamber. Big sucker- about 30 feet long. It was "decommissioned" (scrapped) for the stainless steel.

Re: 90 volt DC motor Controllers
gotchya...BTW what is a film sputtering machine ?
only thing i know about sputtering is old engines and black deposits from lights, like neon , fluorescents and other such items..

Re: 90 volt DC motor Controllers
Ya- I had an old Chevy that was prone to sputtering too!
Thin Film sputtering is a process to deposit thin, very controllable films of materials unto a substrate.

We were depositing Copper, Indium and Gallium on sheets of glass to make solar panels.

Re: 90 volt DC motor Controllers
cool... sounds like they were the Amorphous type, or thin film technology.
Re: 90 volt DC motor Controllers
Amorphous solar cells are thin film silicon, ours are CIGS: Copper, Indium, Gallium and Selenium.

Re: 90 volt DC motor Controllers
ya, i got that later on after reading more
Re: 90 volt DC motor Controllers
Just a jump in here...
I saw selenium mentioned and remembered that many years ago, if a selenium rectifier was dissembled, the paint was stripped and contact was made to both sides of a plate you had a primitive solar cell. Guess i'm just a bit surprised it took so long to get from there to here with the technology!

Re: 90 volt DC motor Controllers
Yes, there are many combinations of materials that exhibit the photoelectric effect, besides selenium. The tricky bit is to get enough conversion efficiency to make building it worthwhile.
