    An example would be helpful.

    I have never heard this term. Is it something that was translated from another language?

    Maybe it's a poor translation of "industrial power supply" ... maybe it's designed for higher temperature range, maybe has some dust filters ...

    Hardened against an Electro Magnetic Pulse (EMP)?

    Yes, industrially (and in applications like aviation, space flight, and the military) electronics in general can be/are "hardened" or shielded for EMP and radiation.

    I didn't mention radiation as it would seem to affect chips... me having forgotten that power supplies these days have their own chips.

    I seem to recall that one reason the Russians had tube technology in their military planes was their better ability to survive an electro-magnetic pulse; I don't know if they still use valve technology.

    The amount dwindles each year but the US and the Russians still have some tube based technology in use.

    Don't the really powerful transmitters still use tubes (Klystrons)?

    I know very little of this technology.
