Each one is fed independanlty across a different phase. There are 3 taps plus neutral for each supply. 24v and two 18v which is turned into +24vdc, +15vdc and -15vdc. The +24vdc is the one that drops out each time the mill is started. I suppose a transformer would work, but was looking for something that would be more stable and larger. I'm still in the process of aquireing machinery for my shop and would rather have a dependable powere source than modify each unit.
