I have a couple of basic questions regarding power supply output connections.
I want to connect a supply to a DAC that requires 24 volts and has only two power input wires Red/Black (+/-) and I have a power supply that has three output wires: 24volt+-0-24volt- ...do I connect the +/- to the red and black wires and connect the 0 to chassis ground? Or the 0 to circuit ground?
Or do I need a power supply with only two wires (Red/Black +/-) ?
Second question is, I want to power the TDA1545A seperately and I have a 12volt 5amp supply that I want to use...am I correct that I can use this supply and the TDA1545A will only draw the current it requires without frying it or am I going to have a melt down?
Thanks for any information.
T.D.

Sorry, second question, yes the TDA will draw what is required.
TBH a 5 amp PSU sounds as though (and I may be wrong.. haven't seen it) that it isn't designed for high regulation and low noise... which is what you want for a DAC. It won't do any harm as long as the 12 volts is stable (if that IS the voltage you need... would have to look the TDA data sheet up).

Mooly- you're fast on the trigger
lol
Thanks for all the replies.
I double checked, the DAC itself can use anything from 12 to 24voltsDC and the TDA1545A requires 12volts.
The 5amp figure in my oirginal post is a typo...it is actually a 12 voltDC 1.5 amp regulated linear supply that I bought at a military surplus store, but with tight regulation and low noise now in mind I have decided to build one of these supplies for my project to power the TDA1545A:
