A re-upload of my Christmas tree, the other video shows an error. Run on an Allen Bradley SLC5/03 PLC with 2 PC's controlling it with AdvancedHMI. The tree has almost 500 lights cut into 12 volt sections and just over 1,000 feet of wire. The PLC has 6 16 output cards for a total of 96 outputs, each card running one section of all strings. It is powered by a 12 volt 30 amp fan cooled power supply, I originally had it run on a 3 amp power supply but as soon as I connected over 1/4 of the lights they began to dim, and then shut off completely when I added over 1/3 of the lights. With the voltage adjusted down to 11 volts (to be gentler on the bulbs) it pulls just under 16 amps with all lights on - just under 200 watts total.
