When An External Power Supply has Too High a Voltage

I've noticed most external power supplies (wallwarts,adapters) have
safe voltages like 5V, 6V, 12V, 24V, 48V.
I've yet to notice external supplies beyond 48VDC.
Example:

I guess beyond 48V it gets specialized.

What if my product idea needs an external 100VDC 1A power supply?
(There's no space for the power supply inside the product.)

120VAC outlet---cord--->100VDC external supply----cord---->product

The product goes in an office and the cords will be accessible to the
public. Typical approved wire for the cords are used.

Do I get into trouble with safety regulations?
I believe the whole chain should be no more dangerous than an approved
120VAC extension cord.
