I have made a servo PSU. It simply rectifies mains voltage to give me 325V DC. https://picasaweb.google.com/lh/photo/HdNJXBD5wPqDUi9E8C46HQ?feat=directlink https://picasaweb.google.com/lh/photo/dTcU2i7GYh53xSrqjh--BQ?feat=directlink There is a bit of extra componentry in the box to discharge the caps on power-off and to switch in a resistor for soft start, but basically it is just a rectifier and some caps.
I am a bit puzzled about the status of my -V. I guess that my 0V will be a few volts away from neutral, which is a few volts from earth. Should there be an explicit connection between my DC- and earth, machine 0V, mains neutral, none of the above? I think perhaps I should have a 1:1 transformer to float the DC, which would then allow such a connection. -- atp "Torque wrenches are for the obedience of fools and the guidance of wise men" ------------------------------------------------------------------------------ Special Offer -- Download ArcSight Logger for FREE!
