D/C amps to A/c amps
by james3838 on 09/23/05 at 11:25:23
I have a power supply that is rated at -48VDC at 75 amps or app 3000 watts that will be powered through a transformer that is fed with 208VAC 3 phase. I am trying to determine what the A/C amp draw will be on the 3 legs of the 208VAC to use the appropriate sized breaker. Can anyone share this formula with me? Thanks

The power supply should list the input rating also.
But I found a Power Supply message board. You could post your question there: http://www.currentsolutions.com/messageboard/view.cgi
It would be cool if you posted here what their reply is, so others will know. :)
