Part Number: 782857-01

The National Instruments PXIe-4112 programmable power supply (Part Number 782857-01) is a high-performance module designed for the PXI platform. It offers a total output of 60 Watts distributed across two isolated output channels, each capable of delivering up to 60 Volts DC and a maximum output current of 1 Ampere. With a programming resolution of 2 mA for both output voltage and measurement, this power supply ensures precise control and monitoring of power delivery. The voltage accuracy for the PXIe-4112 is rated at 0.12% + 55 mV, complemented by a current accuracy of 0.01% + 500 μA, making it suitable for applications requiring stringent performance standards. The module also incorporates remote sensing capabilities to directly measure voltage losses at load terminals, thereby maintaining accuracy during operation.

For voltage regulation, the module guarantees a deviation of no more than 0.01% + 300 μV, while current regulation is maintained within 0.01% + 300 nA, ensuring reliable power delivery. The design prioritizes low ripple and noise, with values under 24 mV peak-to-peak and greater than 4 mV RMS for the voltage output. The transient response time is notably quick, at 40 ms for full resistive loads and 100 ms for no load conditions, providing swift stabilization of output voltage levels to prevent over or under voltage scenarios.

Operating within an environmental temperature range of 0°C to 40°C and with a storage temperature allowance of -40°C to 70°C, the PXIe-4112 is engineered for durability and longevity. Additionally, it adheres to stringent EMC standards and complies with electrical equipment safety regulations, including IEC 61010-1, EN 61010-1, UL 61010-1, and CSA C22.2 No. 61010-1, making it an optimal choice for demanding industrial settings. The compact dimensions of 2.0 cm x 13.0 cm x 21.6 cm further enhance its integration into various control systems.
