Hello Mike,
24 April 2017


I  use  52V  at  57  Amp  HP  SMPS units, they can be put in series or
parallel  with no mods, and i believe addin a negative voltage bias to
the  internal  voltage trimmer pot will allow about 65V out, although I
haven't  tried  it. Hwere are some UK brand new ones, but you see used
ones  for  a  lot  less, but not very often from the UK. They are cool
running  and electrically very quiet. The fan is quite loud though. If
anyone knows of similar amperage variable voltage and variable current
limiting supplies that go to 100V or more, I'd be very interested...
