I received the 230 avr from Tom.... here are my new numbers :
no load
237 volts....118.7 each leg
10 amp load on both legs
238 volts
109.7 on 1 leg
135 on the other
10 amp load on 1 leg
124 on 1 leg
116 on the other
The growl is much worse with an unbalanced load.
If I wanted to use it for a dedicated 230 or 115 gen set it would
probibly be fine. To use it for a 230/115 load it looks to be too much
of a spread for anything with a "sensitive" load.
I plan to call Tom again on monday to see what he has to say.
This only reinforces my decision to purchase the "stamford clone" next.
Again, I will post results.
Thanks for your time,
Gary
