Scott:
From the specs you have given that should work. I would, however,
consider running a separate single phase line to the controller for it's
power. Even the best phase converters will have some problems with low
voltage on the "generated" third phase leg. The other option is to make
certain that the control's power is derived from the 2 lines that are
actually coming from the original single phase source. This would require
less rewiring and adding the dedicated outside single phase line.
