Hi Dick,
That sounds like a rather poor regulation for a 3-phase power supply.
Is your mains voltage already dropping?
I guess the transformer might be a bit too small to deliver 10KW, or is the
3-phase p/s heavier then 45kg?
Here at 7,5KV the B+ is dropping to 7,25KV loaded by 3A (load C=2mmF)
I had a look at the DX4 manual. They use a simple pi-net with a balun
output, no pi-L?
How good is the harmonic supression of it? I calculate just 30dbs on the
second and 43dbs on the third harmonic.

The circuit diagram of the Emtron DX4 3 phase power supply can be found in
the
file section on
<>
It use the plate transformer in delta on the primary and star on the
secondary.
A FWD and 58 uf cap bank is used, output 3.2 kV, @ 3.5 amps peak the B+
drops to 3 kV
