Negative 0-30 Power Supply

Recommended Posts

Guest markdem

Hi All,

I built the 0-30v power supply a few years ago and now would like to rebuild it with the new mods.
My idea would be to make 2 of them and make the negative one track the positive giving me a nice dual polarity tracking power supply. Question is, how hard would it be to make it output a negative voltage?

Thanks

Simply build another power supply completely separate from the first power supply and use its "+" output as 0V and use its "ground" output as its variable negative voltage output.
Even the transformer and any meters must be separate.
