NI Smart Camera Power Requirements
Caution Use the NI Smart Camera only with a 24 VDC, UL listed, limited power source
(LPS) supply. The power supply should bear the UL listed mark, LPS. The power supply
must meet any safety and compliance requirements for the country of use.
The smart camera uses a nominal 24 VDC power source. The smart camera
accepts power within the range of the industry standard IEC 1311 input
power specification (24 V +20%/–15% with an additional allowance for an
AC peak of +5%). Refer to Appendix A, Specifications, for complete
power requirement specifications.
Caution The 24 V external lighting strobe is an unregulated output dependent on the range
of the power supply provided to the smart camera. If the power provided to the smart
camera is +20%/–15% with +5% AC ripple, the external lighting strobe output could be
as high as 30 V. If the provided power exceeds the input voltage specifications of the
third-party lighting controller, do not connect the 24 V lighting strobe output to the
controller to prevent damage to the controller. Use a power supply with tolerances that
meet the requirements of the controller, or use the 5 V external lighting strobe.
