Re: [CAD_CAM_EDM_DRO] another marriss help question !!

well.... plenty of volts.... what about amps? Usually a transformer with
that kind of voltage, has a trade-off of very little amps.... As far as too
much voltage, well you should not exceed over 25 times the amount you motor
is rated. Also your circuits for your dc conversion will eat some of the
volts....
