My static display is up and running but I am having problems with lights. All the strings are powered by separate plugin transformers all 24V with the standard push button controller box and have differing currents ranging from 240 Ma up to 1500ma and they are starting to fail whether by overloading or because they are old, I do not know. So I really need to next year start thinking of a different Power supply. To start my extensive list of questions regards this, and other things, I will start with this one... The transformer is reducing the power output from 240v to 24v AC which then enters the Controller, what power is actually being distributed from that controller is it still 24V( and I assume is now DC) or is it some lower value ie 12v. I may have to cut a controller off and experiment with the leds just to see what power it takes but at the moment thay are all up so am a bit hesitant to do so until the season is over. Bearing in mind the above, I plan to get a Ray Wan DMX controller board for next season with PSU, does this board power those led Strings or do I need a supplementry PSU to power them? I have seen circuit diagrams using separate supplies and the actual board is just a trigger to switch on and off the leds but these may be SSRs... its starting to really confuse me now. :-\ Is this the circuit that I should use or is it wrong I understand that for each additional controller, I will need an additinal PSU for it Your Kind Help would be appreciated very much.
