I just received a 5 volt power supply that has identical cut-off wires on each end --no AC plug. Does it matter which end receives the AC plug , and which wire on that plug is hot? If it matters, how do I tell? Thanks!

Obviously the supply and output connections have to be correct, is this a switching supply or linear regulated or un-regulated? and make or model?
Al.
This is to supply 5 volt power to stepper drivers and BOB for 3 axis system. Its sold by Keling, Taiwanese made, what may have been a name plate literally cut out with probably a utility knife, model 7202C-3, P/N 1333561, but these may be meaningless. (Just Googled the model # -its a power supply for IBM Lexmark printer!) Wonder why he cut off the plug? Maybe it wasn't conventional 110 plug...
I see when I look more closely which wires are for 110 in, which for 5 volt out. One of the 110 in wires has a stripe on it -that one hot I presume? thanks!
