What budget are you looking at?
I'm kind of afraid to ask, what with all these Ali Express links being thrown about.
A bench supply will do that for $2000 or less, and it'll work right out of the box.
Well, beware of shitty cheap bench supplies that aren't actually capable of rated load. The good ones probably start in the $500 range, or less if you find a nice vintage, brand name supply.
You could make a custom converter module, but that would cost a lot of time, and may not be reliable (if you're not too skilled in such arts). There may be adjustable modules that fit the bill, which may be Chinese junk or proper quality things, with prices scaling to suit. Don't know so much about that, offhand.
An AC-DC power supply module will get you the base supply (12V would be possible with a SEPIC or buck-boost topology, 24V with buck), but not a wide range of control unless it's made for that, in which case what you have is probably a bench supply.
A power supply module could perhaps be modified for the adjustable range, but that would also require quite some time and skill (firstly to reverse-engineer the existing design, then to make the appropriate modifications to it).
