Review on DZS Elec Converter Adjustable Regulator by Stoner Fulton

I replaced the fixed current LED driver with this to reduce the LED current on my polymer printer a bit. This board works great and is pretty easy to use. I reduced my rating to 4 runs because the controller run time is a little slow. The regulator takes about 250ms to reach the desired voltage after being idle long enough to discharge the capacitors. It takes about 100 ms for the regulator to reach the regulated voltage (either the desired voltage or the current-limited voltage) when the turn-off time is relatively short. I can watch my LED disappear. That's my only complaint, otherwise a nice little tool to have around. However, I need to find another board for my specific application.
