I think it's more like you have a 110 VDC power supply for the motors in
your machine and you want to convert that to lower voltage for
electronic controls. Variable input voltage is good because when the
motors kick on you might see voltage jump around.
17 years ago I was a draftsman drawing wiring diagrams for process
equipment. Pretty sure I've seen something like that.

I don't think it is a misprint, I have seen other high-voltage input
DC:DC converters (you can find some from Sager/Powergate), but they're
much rarer than things which have a top-end input voltage maximum of
around 76VDC... Really curious what sort of weird industrial
applications are relatively low wattage at a couple hundred watts load
for a device, and need that kind of input.

I wonder if that is a misprint. I know a lot of power supplies that
actually "don't care" if the input is AC or DC. So inputting 120 VAC
works more-or-less the same are 120VDC. Off-line switching power
supplies were a great innovation.

I know such things exist but have never encountered them in person,
where would you have 140 or 150VDC power?

Unfortunately the prices (even assuming a discount) look
prohibitive.
