Hey, anyone out there have 3-phase hook-up advice?
So, I have a couple amp racks, each with a 3-phase power distro and 3 XTi or 3 iTech amps. The power distro breaks down the legs into 3, 120V circuits (common neutral). Each amp plugs into a separate circuit. Given a linear load, the neutral line should result in close to 0 voltage. It seems like amps would present close to a linear load, but with these i-class power supplies, I'm less certain...and was just guessing to begin with. ;-)
2 Questions -
1.) If running the same program on all 3 amps, considering the switching power supplies, would they be considered a 'non-linear' load and risk over-loading the neutral leg? I haven't been able to measure the neutral in use and am real curious if anyone has.
2.) Beyond #1, would it make more sense to wire across the 208V legs instead? Seems like this would reduce the current flow/thermal dissipation, and maybe increase the headroom/circuit stability?
Thank you for your thoughts!
