I would like to expose my experience trying to feed a 150 Leds ws2811, that I want to test with Adafruit´s strandtest.ino
the strips specs are:
5M / 150 RGB LEDS WS2811 IC control 3 LED Chip Work Voltage: DC12V Work Current: 3A
I am testing the strip with 2 different power supplies.
1 (12V / 1200mA / 14.4W). It seems to be reading the information correctly, but not all the Leds react. This power supply is obviously not enough to feed the strip, that requires 36W / 3A
2 (12V / 5A / 60W). This power supply should be more than enough to feed this strip. Nevertheless, when I connect it, every Led turns on with a bit of red & green. When I trigger the strandtest I see that it is also reacting to this information, but every Led continue being ON with this red & green colour... This is very weird. Should I assume that it is a problem of the power supply?
hope you see the light where I see only confusion!!!
