I got this power supply originaly for LED's and it has the following 360W, Input 100-240V 50/60Hz Output; 5V, 12V, 24V, 36V, 48V. This is where I lose it. There are nine screw lugs, three are for L,N,G., I get that, The remaining lugs are +V,+V,+V, com, com, com. So how does the power suplly deliver those different output values. Can I connect to any of the three or is there a difference? I'd like to use for my 3D Printer.
