National Instruments NI sbRIO-960x 用户手册

The sbRIO device requires a power supply connected to connector J3. 
Refer to Figure 4 for the location of J3. Refer to the 

 section for information about connecting the power supply.

Power supply voltage range....................19–30 VDC

Power supply current limit .....................1.8 A

Power connector internal fuse ................2 A non-replaceable

Total power requirement 

= P

 + P

 + P

 + P

,

where 

 is the consumption by sbRIO internal operation

 is the consumption by the 3.3 V DIO

 is the consumption by the 5 V voltage output

 is the consumption by installed board-only C Series 

modules.

You must add 20% to the calculated or measured total power requirement to account 

for transient and startup conditions.

Maximum P

.........................................6.0 W

Maximum P

.......................................1.28 W

 = Total DIO Current 

× 3.3 V/0.85

Maximum P

.........................................11.1 W

 = Total 5 V Output Current 

×  5 V/0.9

Maximum P

.......................................3.3 W; each installed C Series 

module consumes up to 1.1 W

The sbRIO device is 1–2% more efficient with a 19 V supply than with a 30 V supply.
