National Instruments PXIe-4112 and NI PXIe-4113 PXI programmable power supply modules

National Instruments has announced its latest general-purpose programmable power supplies for its PXI-based automated test systems. The NI PXIe-4112 and NI PXIe-4113 modules provide high power density, saving rack space and simplifying design by eliminating the need to mix multiple instrumentation form factors. When programmed with NI LabVIEW software and paired with a range of PXI hardware instrumentation, the power supplies can help engineers create a complete, customised test solution.

The modules feature two 60 W power supply channels in a single PXI Express slot. The NI PXIe-4112 power supply features 60 V at 1 A per channel and the NI PXIe-4113 power supply offers 10 V at 6 A per channel. The two channels can be combined to create a single 120 W channel. To easily synchronise measurements, engineers can combine the power supplies with more than 1500 PXI modular instruments ranging from digital multimeters to RF analysers and generators, and simply trigger the instruments across the PXI chassis backplane.

Engineers can quickly take measurements using soft front panels with an interactive user interface or build fully automated applications using the LabVIEW example programs that come with the power supplies. There are example programs to perform voltage sweeps, source DC current and source DC power. With seamless LabVIEW integration, engineers dramatically reduce development time while improving system scalability for a range of applications.
