I appreciate this too. Further investigation on my part might shed
light on a cause for both of my dimmer failures: too high of input
voltage! Even though advertised as 12-24VDC input, I tend not to trust
this figure and, after looking at the components inside, I think it's
12V, period! Unfortunately, the driving supplies I had been using for
this were more like for standard Ham radio, 13.8 VDC. Perhaps this
higher voltage could not be handled by the dimmer components.

** You have never posted what PSU voltage you have been using ???

The rating of 12-24V applies to the LED array it is driving.

You cannot use a 24V supply, connect a 12 V LED array and set the control half way.
