Example power requirement calculations:
For an NI sbRIO-9606 with an RMC board drawing 1 A of current from the
5 V output, 100 mA of current from the 3.3 V output, 30 mA total current
through the 3.3 V DIO pins, and a USB device pulling 200 mA, calculate
the total power requirement as follows:
P
int
= 8.10 W
P
3.3V
= 0.41 W
P
DIO
= 0.12 W
P
5V
= 5.56 W
P
USB
= 1.11 W
Adding 10% for transient conditions, 15.55 W × 1.1 = 17.11 W
Total power requirement = 17.11 W
Note These calculations are intended to approximate the maximum power requirements
for an NI sbRIO device system. For a more accurate estimate of a specific application’s
power consumption it is recommended to directly measure a board running the application
in an environment representative of the intended use case.

The SD specification allows 200 mA maximum current draw for an SD card. If your SD card does not specify maximum
current draw, assume 200 mA.
