MeanWell DAP-04 for dimming meanwell drivers.

Was reading up on dimming methods besides a basic potentiometer and was looking into controllers but came across this product by meanwell. It is recommended to be used with all their B drivers of the HLG, ELG, and LPF-D series. Has anyone used one of these before? The price is cheap and can control up to 4 drivers, I'm not totally sure if anything else would be required. Hopefully some of those with info on DALI lighting can chime in to explain.

I work on a cheap controller that manages the power and time of lighting the lamps. The basic functions are:
- Light Timer
- PWM power control (theoretically you can control any number of Meanwell type B power supplies)
- Power meter

A few similar projects can be found here on the forum, but none of them is perfect. That's why I decided to do my own. After finishing and testing, it will provide controller plans for everyone for free.
