My phase converter holds voltage better than 5%. That's not because of
some magic, but because the two idlers are big and they have
capacitors attached to both legs.
If you have a big idler, and properly sized run caps, that apply to
both legs, it will have great regulation.
For $100 or $200 you can have a great phase converter.
Run your 10 HP Baldor just like you did, but put 80-100 uF run
capacitors between legs 1-3 and 2-3. Very likely, the output of that,
at low loads like 3 HP, would be extremely well behaved.
Hey Ig,
Leg 3 is the wild leg, right?
I do not like the word wild, but yes.
How big are your idlers?
10 and 7.5 HP
I forgot to mention perhaps the weirdest thing: the wild leg off the Baldor
is LOWER than the 240 V input!! Izzat possible? I'll have to check it
again!
No surprise
In googling diy rpc's, I saw one with 3 panel volt meters. How cool is
DAT??
very cool, I have one and want to install one too.
