Voltage "divider" after PSU to highten the resolution?
FriedMule:
I am sorry that I have not been clear on why I think a 0.1mV would be great.
I already have a standard Korad 10mV supply and is normally fine for just delivering stable power, but I am becoming wary interested in how components, chips and circuits are behaving under different voltages and 1mV is to big steps, it's almost like the Korad.
tggzzz could you please tell me how you have made your 2020 PSU, sounds like what I need? :-)

Power Designs are a bit of a 'Relic' ;) If you want serious control then buy a DC voltage Calibrator >:D

How. Much. Power.? 1uW, 1W, 1MW? There's a big difference between each of those.

Be aware some Power Designs PSUs are 115V only. With the 2020 it is only necessary to change the transformer taps; soldering required.
Manuals, including schematics are available free on the web.

How much does it cost ?? I am thinking of designing one using PIC Microcontroller.
