I grabbed my multimeter to see what kind of voltage the power supply is putting out, and it’s giving me 52V. The output is rated at 24V, if you're getting 52V then I'd say you do indeed have a bad PS. Further, if its dumping 52V out the output it may have damaged the replacement controller too. My guess is you'd need to replace both.

The input rating shows a range of 100-240v, so even if it was fed 240v, the output should be the rated 24v. This either has a regulator or a buck converter in it to drop the voltage.
