Chris, I am just being curious, your BP currently has a 3-phase main transformer that supplies the servo drives and maybe other things? The 3-phase Xfmr expects 415 VAC on each leg which ends up as 100 VDC for the servo drivers? What voltage and phase do you want to input? The BP isn't that big of a machine, I am having a hard time understanding why you need a 100 pound transformer.
