Rohde & Schwarz NPA501 power analyser
Details
The Rohde & Schwarz NPA501 is part of the R&S NPA series of single-phase power analysers. It is designed for AC/DC load or standby current characterisation with an accuracy of 0.05% and a low current measurement of 5mA. The analyser requires no additional tools for graphical analysis and compliance testing.
It has numerical displays of 26 critical parameters with a fast update rate of 100ms, and an auto-range function to enhance testing efficiency. Furthermore, the product features frequency and adaptive filters to eliminate unnecessary noise, ensuring smooth and accurate results. The display content can be saved to a USB flash drive or shared through the Ethernet and USB interfaces.
Unique to this series is the timestamped logging to CSV for a nearly unlimited period. However, if further enhanced measurement functions and graphics are not required, the R&S NPA101 is a cheaper option. And if the evaluation functions have to be in line with IEC 62301, EN 50564 and EN 61000-3-2 industry standards, the R&S NPA701 is recommended. For the full range of available functions (per model), please see the table in the images.
Take note, some images are of the NPA701 model, but are comparable to the NPA501.Specifications
