Power Supplies

Engineers should consider specifications such as output voltage and current range, resolution, accuracy, and stability. Features like programmability, remote control, and integration with automated test systems are also important. Safety is a key factor, and NI power supplies include protections such as overvoltage, overcurrent, and thermal shutdown to safeguard both the instrument and the device under test.

Power supplies deliver controlled DC voltage and current to power devices under test during evaluation, validation, and production. Engineers use them to simulate operating conditions, verify power behavior, and ensure components perform reliably under load. In reliability and stress testing, power supplies help simulate voltage drops, surges, and thermal stress to identify failure points and ensure long-term durability of components and devices. They’re commonly used in consumer electronics, automotive, and aerospace test applications.

Yes. NI PXI power supplies can be synchronized with other PXI instruments using NI-TClk technology. This enables coordinated timing across multiple channels and instruments, which is critical for system-level testing and power-event correlation. 

NI power supplies deliver precise control, fast response times, and integration with automated test systems. Their programmable capabilities allow engineers to define voltage and current profiles, automate power cycling, and simulate dynamic operating conditions. NI power supplies are also supported by LabVIEW and other NI software to accelerate automated test.
