The load bank built by [Debraj] is actually an electronic load, which opens it up for a wider set of use cases than a simple passive dummy load like a resistor bank.

In walking though his junk-box assembled dummy load [Dave] shares some great tips, like using multiple 1% resistors instead of shelling our for one large and accurate power resistor.

I'd like to ask if it's safe to use a PSU to just power CCTV Cameras and recorder (which uses 12v) without using a computer. (are there things i should watch out if i do this like using dummy ...

Calculate the slope using a dummy moment, m, in addition to the dummy load, Q. In this case, the moment equation for the reactions of the shaft will also include a term containing m.

But sometimes, when you think you have seen it all, you haven't. I came across a fascinating article n the January 2010 of Power Electronics Technology , entitled “Testing Power Converters Using a ...
