A-Eberle PQ BOX 50 Power Quality Network Analyser

Network Analysis for Low-, Medium- High-Voltage Networks.

The A-Eberle PQ-Box 50 is a powerful, portable and very easy to use Power Quality Network Analyser for a wide range of industrial and utility applications. Due to its integrated power supply, robustness and compact design, the power analyser is particularly suitable for mobile measurement operation (IP65) in harsh industrial environments as well as for measurement in the electrical grid (600V CAT IV).


A-Eberle PQ BOX 50 Key Features:

  • Powerful
  • Robust
  • Compact design
  • Easy to use
  • Portable / Mobile measurement operation
  • Perfect for industrial / utility applications
  • Integrated power supply
    • Uninterruptible power supply takes over operation for up to 2 hours


A-Eberle PQ BOX 50 Main Applications:

  • Load analysis; energy measurements (e.g. ISO 50001)
  • Fault detection with high-resolution oscilloscope and True RMS value recorder
  • Evaluation of voltage quality according to EN50160 and IEC61000-2-2 /2-4
  • Fault recorder functions
  • Ripple control signal analysis
  • Ripple control frequency measurement


A fast WLAN and a USB interface are available for data transfer.  In the event of a power failure, the built-in, uninterruptible power supply takes over operation for up to 2 hours. The PQ-Box 50 is available in three license variants and is therefore a future-proof investment because of the high sampling rate and the background of changes in the grids!

The PQ-Box 50 works according to the Power Quality product standard IEC 62586 and is classified as follows:

PQI-A-MO-H Meaning: Power Quality Interface Class A to IEC61000-4-30 for Mobile Outdoor applications for the toughest industrial EMC environment Class H (Harsh Environment)
