If you turn a 24 V linear supply down to 19 V, you should derate the current capacity perhaps 25 percent. (Depends on the voltage ahead of the regulator.)

None of mine are really "modern", and I don't know if their few 24VDC models have the pot inside, but I'd bet they do.

Not sure what the authority of that pot is, or if trying to get "all the way" there with a pot might do to the quality of the current.
But, I hadn't thought of that....

Do whatever their modern models are, still have the voltage adjust potentiometer inside?
