ENA460 (PQA)

Power quality analyzer ENA460 is based on NI sbRIO (PowerPC processor + FPGA) and signal conditioning for 4 voltages and 4 currents. ENA460 compact aluminium case mounts directly on a 35mm DIN rail.

Key features:

  • 4 galvanic isolated voltage inputs with antialiasing filters
  • 4 galvanic isolated direct current inputs with antialiasing filters
  • Adaptive sampling frequency
  • Dimensions: 170 x 230 x 120 mm (H x W x D)
  • A/D converter with 16-bit resolution
  • Optional galvanic isolated digital inputs and outputs
  • Consumes less than 20 VA
  • No rotating parts for high reliability
  • Operating system VxWorks

ENA460 analyzer fully complies with the IEC 61000-4-30 standard, class A.
