Re: RE: [CAD_CAM_EDM_DRO] Power Supply Box's

Thanks Mark, I will give it a whirl and see how I make out. I think I'll take extra care to add partitions as needed to keep the RF down. I'd also planned to put a cooling channel on the back which has cool air inside it, then where ever I need more air just put a vent and fan to bring it in. I also plan on filtering all the air that goes into the box and keep it sorta like a positive pressure box just by having several fans pushing filtered air into it at all times.

On another front..

Anyone ever piggy-backed a couple of 1500KVA UPS's together to keep a 220v supply running? Is it possible to do or a waste of time? I'm hoping to just use it to keep the power blip's from ruining a part, if the power did go down, it only needs to run the machine for about 1 minute while the program is stopped and the control computer shuts down. Is there a better way? I'd like to avoid paying $1500 for a solution if possible.
