»PQ-Box 150« and »PQ-Box ONE«

Different installations – same Class A measurement quality

Different installation, identical Class A measurement method

Comparative images from a recent practical example clearly show how the »PQ-Box 150« and »PQ-Box ONE« differ from each other in everyday use.

PQ-Box 150:

  • Proven 3-phase power quality analyser
  • Flexible connection options
  • Individual parameterisation depending on the measurement environment
  • Area of application: Network analyses in industry, energy supply and research facilities, as well as measurement tasks with variable connection and current measurement conditions. The PQ-Box 150 is primarily used in distribution systems, where it offers great flexibility and many connection options.

PQ-Box ONE:

  • Compact, single-phase plug-and-play solution via the mains socket
  • Automatic phase detection
  • No parameterisation necessary
  • Correct measurement direction from the outset
  • Area of application: Rapid fault detection, PQ screenings and recurring measurements in buildings, commercial and industrial settings, and at energy suppliers. The PQ-Box ONE is used directly at the consumer and enables measurements even deeper in the network.

Conclusion:
Both systems deliver the same high-quality, standard-compliant measurement range in accordance with Class A of IEC 61000-4-30 Edition 4. However, the PQ-Box ONE significantly reduces installation costs and is particularly suitable for fast, decentralised measurements close to the consumer. The PQ-Box 150 remains the right choice for more complex situations with variable connection conditions in the distribution network.
