I have a 3-CH DMX controller (5-24V, 5A/ch, common anode) from amazon (don't know if links are desired here) and a 12V 100W MCPCB LED panel, which unfortunately has a common cathode. The panel is equipped with 200pcs 3.0V 0.5W LEDs and has two different LED types (bi-color). So I would connect to the panel with two channels from the controller to change the brightness for each channel of the panel. Because of the common cathode wiring of the LED panel both channels are up, when changing brightness.
I would like to modify the DMX controller outputs so that it can handle this panel. Can you recommend which MOSFETs I should use and how I wire them? Or another solution that is suitable for this project. Per channel I have 4.16A in the line.
Thanks a lot!
Edit: I'm attaching an image and pinout of the controller (for the led panel board i don't have schematics, but the manufacturer confirmed that this panel has common cathode wiring):
