FAQ

Product-specific questions

Product-specific answers based on available technical information.

What output does the NI PS-15 provide?

NI identifies the PS-15 as a 24–28 VDC industrial supply rated at 5 A and 120 W. Consult the manual for operating limits when adjusting voltage or sizing the load.

Is the PS-15 a desktop laboratory power supply?

NI classifies it as a DIN-mountable industrial power supply. Its manual describes an output-voltage potentiometer and DC OK LED, rather than a laboratory-style numerical display.

How do I check compatibility with my NI system?

Use NI's CompactDAQ or CompactRIO power-supply accessory guide for the exact controller or chassis model, then check its voltage, current and wiring requirements.
