Hi,
I would like to build Adjustable DC Power Supply 0 - 100V DC / 1A to control my Magnetic Chuck on Surface Grinder.
Anyone can help to make my dream come true?
Regards,
Andre

Should be very simple with 2 rectifiers and two SCR's, a POT and a few other components.
Google for full wave SCR control.

If you don't mind, just bring me through the site Al I'm not sure what I looking for
I will see if I can find a schematic and post it.

Andre, you may be able to use a DC varriable speed control. Here is one on ebay that should work for you. (not mine)

This should work at not much cost, an off switch could control the relay, contacts only are shown.

Al, I see your attach. What is specification for Toroidal transformer & Rectifier Bridge?
Another option would be an autotransformer and a rectifier.

The bridge can be any off the shelf item rated for 200~250v at the current you want to supply, the price difference is very little for higher rated versions.
The toroid can be any ferrite ring type found in PC power supplies etc, just wind one layer of around 18g on half in one direction, half in the other.
The Triac and Diac are older part numbers but they should cross over to current numbers, and they are not that critical for this application.
