Re: DPS5020 dual power supply build
the metal of the usb is frame-ground - it should be seperate from the 0v pin.
but that's not important, what matters is the side that plugs into the psu - that's opto-isolated from the usb side.
so you should be o.k.
check it - plug the adapter in and ohm between the usb socket and the ground on the psu module
