Hi Guys,
I'm putting up some 12v RGB 5050 LED Strips for part of my Christmas display. The total run length is 14metres. It would be run something like this:
Power Supply > Wire to First LED Strip (10m) > 5m of LED Strip > Joiner > 50cm of LED Strip > Joiner > 2.5m of LED Strip > 4m Joiner > 3m of LED Strip > Joiner > 3m of LED Strip
There are 150 LEDs per 5 meters, which equals 3 amps (according to the specs) so all up I should have 8.4 Amps of Lighting (14/5=2.8, 2.8*3=8.4). The wire I am using is Cat 5.
First question, does this mean the minimum size of transformer should be 9 Amps?
(I have a power supply that is 12v AC, 200VA, 16.7 amps. I'd assume LED's run on DC though. This isn't specified on the strips.)
Second Question, the Strips came with RGB controllers, model number IR44B, this is all I know about them. To run this length, would I need an RGB amplifier?
Thanks!
* My second option would be to run them with two separate power supplies, would these calculations be correct?
Section 1: 8m
3/5 = 0.6
0.6*8 = 4.8 amps
12 Volts, 4.8 amps
Section 2: 6m
3/5 = 0.6
0.6*6 = 3.6 amps
12 Volts, 3.6 Amps
