Thank you for your advice. And I know they do work with them in general, not sure what the deal with with analog negative input.

How to connect Mean Well LDD drivers for aquarium lights | Fishroom’s Blog
The power supply provides a constant voltage red wireswhich must be at least 3 V higher than the voltage of the series of LEDs. Technical cookies The technical cookies on this website allow you to add products to your shopping basket and pay them at a later time, for example.

But if Arduino is powered by some separate power source my case grounds need to be linked, otherwise there will be no dimming going on.
Therefore, the driver operates as a device that transforms constant voltage into constant intensity. Nowadays LDD drivers from the brand MeanWell are increasingly used to power and control dimming high power leds in lighting proyects such as aquarium lights canopies and fishroom multiple aquariums lighting.

Meanwell LDD-H Driver
To do this, it sets automatically the output voltage neccessary to produce that current through the LEDs. My reading of the datasheet is that it has a PWM dimming input which accepts voltage levels and frequencies that are just fine for an Arduino PWM output.
If you lose connectivity between the drivers and the Arduino, ldv LEDs will run at full blast, which could potentially fry your corals. These cookies have different retention periods. Contact View more Contact.
