ENA450 (PQA)

Power quality analyzer ENA450 is based on a modular National Instruments Compact RIO hardware with a configurable number of voltage and current inputs. The ENA450 mounts directly on a 35mm DIN rail.

ENA450 is available in four variants: ENA450.EB, ENA450.EC, ENA450.NB, ENA450.NC.

Key features:

  • 4 voltage and 4 direct current galvanic isolated inputs with antialiasing filters. (ENA450.EB, ENA450.EC)
  • 3 voltage and 3 indirect current (with current clamps) galvanic isolated inputs with antialiasing filters. (ENA450.NB, ENA450.NC)
  • Adaptive sampling frequency
  • A/D converter with 24-bit resolution for high precision (only for ENA450.NB, ENA450.NC)
  • Optional digital inputs/outputs
  • Consumes less than 10 VA
  • No rotating parts for high reliability
  • Operating system VxWorks

ENA450 analyzer fully complies with the IEC 61000-4-30 standard, class A.
