Art,
Are these converters able to be controlled by a 0- 10 volt signal?

well, because I have a dealer sample at work which just plugs into the AC
line. They say to derate the motor by 50% for single phase input. I was
thinking of putting them on Ebay, but haven't a clue what they are worth. It
seems they might solve the problem of having a

one is mostly heat sink and says AC Variable speed motor drive. I'm pretty
sure its rated at 50HP.
