P10 Power consumption

When determining your power needs, it is suggested that you take the more conservative numbers.  Look at Analysis #2 for more safe numbers.

Power Analysis #1:  Measurements from Patdelaney, calculations from Steve Gase:

Using these panels: http://www.aliexpress.com/item/Free-Shipping-P10-Indoor-SMD-3in1-Full-Color-Led-Display-Module-1-8-scan-320-160mm/1791940107.html

According to the Aliexpress ratings:   Max power consumption is 500W / M2  and Avg power consumption is 200W / M2

Using a multimeter on the output side of the power supply in-line with the P10 panels.

Single Board Power (Amps @ 5v) Notes
Red .85 n/a
Green .61 n/a
Blue .50 n/a
White 1.37 n/a
Butterfly .85 n/a
2x2 Matrix (4 panels) Power (Amps @ 5v) Notes
Red 2.3 n/a
Green 1.6 n/a
Blue
 1.1 n/a
White 3.68 n/a
Butterfly 2.35 n/a

Power Calculations:

You can use the info gathered above to estimate your power needs.  

  • With a 64-panel setup, you can multiply the 4-panel number for white by 16 as a worst-case.  (16 x 3.68 = 58.88 amps)
  • You might consider powering the BBB using the same supply (worst-case: 3 amps   58.88 amps + 3 amps = 61.88 amps)
  • Convert to watts  (5v x 61.88 amps = 309.4 watts)
  • Plan for peaks and Power Supply differences by only using 80% of the planned needs  ( 309.4 watts / 80% = 386.75 watts)  
  • A 400-watt 5V power supply will support the powering of BBB and 64 panels!


Power Analysis #2:  Calculations by JonB, expansion by Steve Gase:

Using these panels: http://www.aliexpress.com/item/A-Indoor-320-160mm-32-16pixels-3in1-SMD-1-8-scan-RGB-P10-full-color-LED/32398118617.html

According to the Aliexpress ratings:   Max power consumption is 700W / M2  and Avg power consumption is 280W / M2

Using the "official" max answer from the makers of P10 panels (on AliExpress) is 700watts per square meter.

They are 0.320m by 0.160m, so each panel is 0.0512 square meters

24 of them would be 1.23 square meters, that is 860 watts.

So, you would need three 350 Watt power supplies (since two wouldn't be enough)

Expanding to 64 panels:

64 panels X 0.32M X 0.16M = 3.28M2  (coverage)

700W x 3.28M2 = 2,293.76W (power consumption)

Planning for 80% usage:   2,293.76W / 80% = 2,867.2W for 64 panels... 9 x 350W supplies.

Note: using 280W (avg) instead of 700W (max) would adjust the number downwards to 1146W for the 64 panels.  It is difficult to interpret the "average" use -- rarely using white?  ...so apply caution when selecting your numbers.
