Power RequirementsThe sbRIO device requires a power supply connected to connector J3.
Refer to Figure 4 for the location of J3. Refer to the Powering the sbRIO
Device section for information about connecting the power supply.
Power supply voltage range....................19–30 VDC1
Power supply current limit.....................1.8 A
Power connector internal fuse................2 A non-replaceable
Total power requirement = Pint + PDIO + P5V + PCSer,
where Pint is the consumption by sbRIO internal operation
PDIO is the consumption by the 3.3 V DIO
P5V is the consumption by the 5V voltage output
PCSer 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.
Maximum Pint.........................................6.0 W
Maximum PDIO.......................................1.28 W
PDIO = Total DIO Current × 3.3 V/0.85
Maximum P5V.........................................11.1 W
P5V = Total 5 V Output Current × 5V/0.9
Maximum PCSer.......................................3.3 W; each installed C Series
module consumes up to 1.1 W
1 The sbRIO device is 1–2% more efficient with a 19 V supply than with a 30 V supply.
