Hey, all. I'm working on a vintage Van Norman mill that runs on 'low voltage' 3-Phase power. A buddy who does a lot of automation saved me a 3-phase contactor from the dumpster at work, and I'm planning how to wire it up. The contactor runs on 24VDC from a power supply that says it will take 100-240VAC at 50/60hz. When I measured the voltage across the legs of my 3-phase plug, I recall having 120ish and 220ish VAC depending on which phases I measured across... If the power supply is just a simple rectifier circuit, would it "care" that I was feeding it with two legs of 3-phase? Is there any reason that I couldn't just use the electric that I already have on the machine instead of having to run a second extension cord from the wall?
