Advice is sought on adding metering to a split rail bench power supply. Is this correct as concerned about earthing/0v loops
I have a power supply with a single output (a paralleled split PSU), and split rails.
I have incorporated switching to enable this to be done. Or is this best if I just used jumpers on the output terminals. But how do I add voltmeters and ammeters?
Chinese dual digital V & I meters will have a separate auxiliary supply from a dcdc isolated supply. The Ammeter is measuring 20A across a shunt.
Single output - No problem, voltage straight across +output terminal and across 0v terminal. Current in the return path from 0v terminal. Believed the correct way to use the Chinese dual digital V & I meters and is not in the positive rail.
Dual (Split) Rail output - Again, voltage no problem as they are both across the output terminals +V 0V and 0V -V. The problem comes in trying to connect the ammeters. Assuming I use the same method as in the single output
