Hi, I'd like to try out the LM675 dual voltage power supply talked about here:
http://forum.allaboutcircuits.com/showthread.php?p=84026
I have a 36 V, 3 A, AC/DC converter that I believe would be called non-isolated. It has a three prong AC plug, and two DC wires, one of which has a connection of about 1Ω to safety ground.
I've read that isolated power supplies are safer, but have never found an explanation why. Would some please explain why?
What problems might I have if I use a non-isolated supply? A noisy ground?
Also what is about the upper limit of current draw on an average electronics project using DC? I'm not sure what size fuse to use.
