How about this scenario:
I will build only the regulator for a power supply, with voltage
control, current control - the whole shebang, but the device
will not connect to the mains at all. Instead, it will have a 24V
DC input plug. Anyone who wants to use it will have to connect
it to another power supply according to the range of Volts and
Amps that they need. Is that a way to absolve myself of any
liability?

Yes. But the question is why?

If you want to do this to make money I think you are on the wrong
track. There will be so much work and costs involved to make it all
into a complete power supply that you cannot expect to get much for
it, considering that complete power supplies are available at rather
low prices compared to the total cost in this case.

I first got the impression that you had already built a power supply
which you wanted to sell, and then the cut off mains cable would be
the simple solution.

But if you plan to build power supplies and sell them you have to
compare the total cost for your customers with what is available on
the market and the prices of such power supplies.

Today we are on the move away from the linear power supplies with
their heavy transformers. The future is in pulse modulated supplies
which are not big and heavy, but such power supplies are very
difficult to design, so it is no future for an amateur builder.

If you want to earn money from building something you should simply
avoid power supplies.
Whatever you build you need to compare it to what is available on the
market, where mass produced devices are a lot cheaper than you could
ever build on your own.

Try to find some special devices, which are not mass produced, maybe
targetting some special user group.
A snail killer for gardens, for example.
I saw how one guy had put up an electric fence, consisting of two
wires 2 cm apart around the garden and he fed 24 Volt to the wires.

When the snails had passed the first wire with their heads and touched
the second wire they died instantly, electrocuting themselves through
the head. "Killer snails" is a big problem in gardens, at least here
in Europe.

Called "Spanish killer snails" in Sweden b.t.w.
One tip I'v heard of is to pick each snail up and
cut it in half with a pair of scissors. Not very
high-tech, but seems to work...

I think the word is "satisfying" ;)

an eco charge only uses 12v though:)
lmk when you post it, want to see what you did
