Differential Receiver board 30amps spec
« on: February 08, 2019, 05:23:14 AM »
Hey guys,
  Im new to this hobby, and this Christmas will be my first show.  I have already brought a F48 and 2 Differential Receiver board.  I also have purchased two 5v 60amps power supplies. 
But, it looks like I have already made my 1st newb mistake.  I overlook the Differential Receiver board 30amps spec.  It looks like I cannot power my receiver board with the 60amp power supply.
So, should I just buy two more amps (5DC 30amps) or is there a low cost way to step the current from 60A to 30A?
Has anyone else had this problem before?

Current is determined by the amount of pixels on the ports. Just reduce the pixels per port to be less than 30amps.

This is about understanding the difference between Voltage (force) and Amperage (flow)

Like David said, its ok to have a power supply with higher Current (amps) capacity than needed.     If you connect 30a of pixels to a 60a power supply, it will supply 30a to the pixels and leave 30a in reserve for other things.

But thats not the same with the Voltage.   If you connect a 12 volt power supply to 5v pixels it will fry them.

David / Mark,
               Thanks for the fast reply.  Yes this makes perfect sense.  I had wondered if that could be the case, but needed to be sure.
Also, I just wanted to say. I really like the xLight software and the Falcon Controllers.  This is going to be a cool new hobby.  I cant wait till Halloween / Christmas.
 :D
