That is what someone else told me, but Delta said no...... I hope you are
correct, because I would be extremely happy with the Delta. Is there something
that I can challenge Delta with, to have them reconsider their statement that
'this shaper will not work with any phase converter' ??

I don't see the need to challenge them. You just want to know the power
requirements for your tool (*your* tool). They can spec voltage, current,
frequency, phase angle, and balance requirements, and perhaps load change
response, but I doubt they go into that much detail. I can't think of any
other power characteristic the machine might require.

It is patently ridiculous for them to spec the power source itself.
(Kirchoff could have a field day with that!)

Your challenge, once you know what the machine requires, is to provide
for it a power source that meets all the specs. I'd be astonished to find
this impossible to achieve with a rotary converter.
