National Instruments PXIe‑4112 PXI Programmable Power Supply

The National Instruments PXIe‑4112 (Part Number: 782857-01, 782956-01) is a 2-Channel, 60 V, 1 A PXI Programmable Power Supply with isolated outputs. The NI PXIe‑4112 facilitates the task of designing automated test systems for many types of applications, such as aerospace, defense, automotive, and component test by eliminating the need to mix multiple instrumentation form factors in a given test rack. Part number 782956-01 describes the PXIe-4112 without an auxiliary power supply. 

This model features a standard output disconnect functionality that allows isolation from the device under test (DUT) when not in use and remote sense to correct for losses in the system wiring. The PXIe 4112 supplies programmable DC power for applications ranging from characterization, design validation, and manufacturing test.

The device operates NI DCPower driver software which is compatible with software packages/application development environments (ADEs) such as LabVIEW, LabWindows/CVI, or Microsoft Visual C/C++. The device hardware can be configured using the Measurement & Automation Explorer (MAX) tool. The PXIe 4112 has a recommended warm-up time of 30 minutes and should be calibrated at least once every 2 years. It has a power requirement of 0.5 A from 3.3 V rail, 0.25 A from 12 V rail, and auxillary power source input requirements of 45.6 VDC to 50.4 VDC, 3.5 A max.

The NI PXIe 4112 Programmable Power Supply has a DC voltage range of 60 V and a minimum programmable voltage level/ limit of 0.1 V. The DC current range is 1 A and minimum programmable current level is 0.01 A. The output power is 60 W/channel therefore, the total output power is 120 W. In addition, the device has an analog output voltage range of 0 V to 60 V. For auxiliary power input line regulation, the voltage is 1 mV and current is 0.2 mA. Remote sense of the PXIe‑4112 has a maximum output lead drop up to 1 v drop per lead and a maximum sense lead resistance up to 1 Ω per lead. The device weighs 15.6 oz., and measures 8.5 x 0.8 x 5.1 in. in physical dimensions. It has a recommended operating temperature range of 0 °C to 55 °C, and a storage temperature range of 40 °C to 70 °C.
