uAmp use for 24v Floodlights
« on: October 05, 2017, 01:36:05 PM »
2 questions on the uAmp

1) I'm using it for RobG's 20W WS2811 floods - they are 24vdc.  I've placed a series 5.6v Zener diode in line with the power input of the uAmp to reduce the voltage that it sees to get some voltage headroom (read that 24vdc is max input voltage).  Will this be OK?

2) I'm installing the uAmps in line and my cabling will vary from 15-40 feet.  Am I better off placing the uAmp on the data inputs or outputs of the flood (currently, I have my first prototype on the input)?


Thanks!

Jim,
  Zener diodes are put across the load with a resistor in series with the zener to limit the current draw.  Do a google search of how to hook it up.  You are on the correct track just have to add one part.  I think that putting the micro amp closer to the output of the controller is better.   More signal for that micro amp to work with.
