3-Phase Power System

Iced:
Hello all, I have a question about the Freestyle and SSR4's.  Is there any special consideration for connecting the FS and SSR4's to a 3-phase Power System?  I'm noticing some sets of 4channels (SSR4) are dimming incorrectly.  By incorrectly I mean when Testing-All-Channels in Vixen 2, the range from approximately 100 down to maybe ~60 seems to be about the same brightness.  Then it dims down to 1, but it's a very obvious "on/off" from 1 to 0.

I guess I'm wondering due to clock timing, if the FS and the SSR4's need to all be on the same circuit phase or if there is some other trick to the setup?

n1ist:
In a 3-phase system, the three phases have their zero-cross points at different times.  If the freestyle is on one phase and the ssrs are on a different phase, they won't dim correctly.

You don't see them on the standard split-phase system we have in most homes as both legs have the zero cross at the same time.

The only thing you can do is to make sure the freestyle and all ssrs connected to it are plugged into the same phase.

Thanks for confirming Mike.  My follow-up question is whether I will be ok with 1 set of FS+SSR4's on one phase with another FS+SSR4's on a second phase in the same DMX universe?  (I also have a few Express's to throw in as well)

caretaker:
Short answer, NO.  Three phase as Mike said is three distinct phase of power and the zero cross setup for the Lynx equipment is set for only single phase (read home use) situations. I have a 6 channel DMX dimmer pack that can be used with either 3 phase or single phase supplies but that is because of how the zero cross setup is designed for that situation.

Iced:
Are there any solutions to my dilemma or am I just stuck with a system I'll never be able to use correctly?  I'm open to anything.
