where
P
int
is the consumption by sbRIO internal operation, including
integrated I/O
P
DIO
is the consumption by the 3.3 V DIO
P
5V
is the consumption by the 5 V voltage output
P
CSer
is the consumption by installed board-only C Series
modules
Note
You must add 20% to the calculated or measured total power requirement to account
for transient and startup conditions.
