One virtue of a CSV is that the output shuts down completely if its shorted. 

They don't really shut down, they deliver a constant
current when they are shorted are quite content to
deliver this current forever.

A foible of CV transformers is they draw the same power
from the AC line no matter what: a 500W transformer will
draw 500 watts with no load, with a 500 watt load or with
a dead short across it's output.

I was filing a patent with the same attorney who represented
Sola (the largest maker of CV transformers), we got to talking
about CV's and it was his opinion that no one at Sola, or
anywhere else for that matter, really understood how they worked.
