I use a solid state one, an older version of this:

Bought on ebay quite a few years ago.
I also have a small Phoenix rotary phase converter, also from ebay. This
one seems to have unbalanced outputs.
I believe it is for motor loads only.

Let me know what you come up with for the 3 phase converter solution. I have
the exact same problem right now to provide power for my 3 3420 tapes and the
3803 controller. Also have 220V 50A single phase coming in the shop (er,
garage), courtesy of the EV charger.

Just to let folks know that I finally moved the IBM 4331 Mainframe this past
weekend
from where it was currently stored to my shop. Pictures are here:

As can be seen in the pictures, it filled a 26’ box truck that I had rented for
this purpose.
Right now I just have it placed somewhat in my shop. Some early tasks will be:
* I have to verify that I have everything. Even if I missed some items,
they won’t be
scrapped. I just need to go over what is currently in my shop and verify
that I didn’t
leave anything behind. I’m mostly worried about cables at this point.
* I have to figure out some way to produce enough “clean” 3-phase power to
run the
peripherals (the CPU is 220v single phase) as I only have 220v single phase
coming
into my shop.
Starting to power it up will probably be a while yet. ;-)
