So, I am looking at purchasing a couple CNC's for my shop. One is a SuperMax Max-1 Rebel VMC, 7.5 HP spindle, and the other is a SuperMax TC-2 lathe, with a 10HP spindle. I live out in the sticks, so 3ph power is about 4 miles away.
I currently have a Johnford SV-40, 15hp spindle. I am running that off of a Phase-A-Matic that I got from MSC (IIRC). I've had zero problems with it.
Someone locally is selling two 15hp Roto-Phase (that's the brand) converters.($900 each) They do not have any voltage regulating stuff on them. I called up Arco (the mfg.) and they said they were good for around 7% variation. I asked if it was possible to install a voltage regulator along the line, and power a CNC. They said absolutely not!
Now, I'm not an electrician by any means. I took me a LONG time to wire up 3 geckos to power my CNC router I built 5 years ago. Not much has changed for me since then.
However.....
Common sense tellls me that they are just trying to get me to buy a new unit...
What say you?
My Phase-A-Matic has a seperate voltage regulator. This can be purchased seperately from the actual converter. Any reason why I can't use that on the Arco? A local distributor can get the regulators for aroung $800 for the 15hp model.....
