Hi Guys n Gals, hope someone can help me....
Silly question but how does everyone hook up their power supplies in parallel and have a single V+ and V- coming out?
I have 3 x (48v 7a) power supplies set up in parallel (48v 21a); and my breakout board needs single V+ and V- input wires @ 48v 21a.
I connected the 3 power supplies to the mains; but when I tried to bridge the 3 individual V+ exiting from the power supplies to form a single V+ lead to the BOB; one of the power supplies starting smoking!
I removed the bridge connector from the 3 individual V+ and it seems fine?
Called in the electrician and he was a little stumped, suggesting it was backfeeding and to get a single power supply instead..
Any help is super dooper greatly appreciated
