bmachine Posted June 7, 2006 Report Share Posted June 7, 2006 Hello, dumb question here.I need to use one of those little wall mounted ac/dc converter for a little 555 based project I am doing. I found an old one that is labeled to have a 9V DC output. But I put my voltmeter to it, it reads 14volts. I then tried a couple that were rated at 24v output and they read more like 28 or 29v.Is this normal? Is it because they need to be measured under some kind of load or something? Is my transformer really going to give 9V to my project or is it going to fry everything by delivering 14 volts?Thank you very much.Bmachine.
