Re: Isolated Power Supplies

'Galvanic' isolation means no common electrical connection, intrinsic means no common electrical connection with a specified safety factor, if unspecified, it would generally mean isolated up to the AC Mains voltage, 120V in the US, 240V most other places.
One of my lab power supplies claims an intrinsic isolation of "up to 1,000V AC or DC." [Yea I take that claim with a large block of salt.]
?
'Galvanic' doesn't include any safety factor. It might be safe to 10,000V or only 10V.
Intrinsic depends on insulation and creepage distance, the distance electricity might leak across. Buy a cheap switch mode power supply at a thrift store and crack the case,?
Trace out the AC inlet, see the isolation zone and then the DC out.
