[QUOTE="TerryK, post: 118996, member: 32169"] Other considerations not depicted: - length of wire from Controller to strings (how long can the wire be before voltage drop?) [FONT=book antiqua][COLOR=rgb(41, 105, 176)]If you are asking how long a wire must be before one sees voltage drop, 0 feet actually. However, for short distances voltage drop in most situations is so small it can be ignored. If you are asking how long a wire can be before voltage drop becomes a problem, it depends upon the wire AWG and current through the wire. In this case with pixels, the number of pixels and their drive level (which I think you have not yet mentioned).[/COLOR][/FONT] - AWG of wire from Fuse to String A (what would be required given the 5A fuse and the length of String A?) [COLOR=rgb(41, 105, 176)][FONT=book antiqua]The wire AWG size would need to be sized to safely carry 5 Amp of current and then adjusted larger in size (a lower AWG number) to give the voltage drop desired or necessary. There is a problem here though. Two hundred pixels assuming WS2811s at 100% White (0.055 Amp each) would be 11 Amp.[/FONT][/COLOR] - power supply specs [COLOR=rgb(41, 105, 176)][FONT=book antiqua]Assuming WS2811s at 100% White, (500 * 0.055), 27.5 Amp, an approximate 330 Watt. If you would drop the drive level a bit a Meanwell RSP-320-12 would carry them fairly well as a minimum. If you would want some headroom in the supply capacity then a Meanwell RSP-500-12. A Meanwell LRS-350-12 would work similar to the RSP-320 model.[/FONT][/COLOR] - type of controller [COLOR=rgb(41, 105, 176)][FONT=book antiqua]Definitely an opinion decision. I like the Falcon F4. A point to keep in mind; the first pixel of each string sees the voltage drop from the supply to the controller and then individually from the controller to that particular string. Essentially, wire size and length from the supply to the controller is just as important as from the controller to the string and in this case, the supply through the fuse to the String A trailing section. Also keep in mind that voltage drop is seen in both the V+ and the V-/GND wires. So voltage drop calculations involving wire resitivity values typically need doubled.[/FONT][/COLOR] [/QUOTE]

The title of our introductory lighting manual contains a three digit number. What is that number? Clue: Display basics forum
