PQA 1500

Measurement and monitoring device for capturing, analyzing, and supervising all key electrical parameters in 3-phase low-voltage networks from 115 V to 690 V.

Advanced measurement functions help reliably monitor increasingly complex network conditions, thereby enhancing the reliability of your electrical system. The PQA is ideal for measuring active and reactive power in machine feeders within main low-voltage distribution boards. With network connectivity and FRAKO Bus interface, the PQA can be easily integrated into the FRAKO data acquisition system in accordance with EN 50001.

PQA 1500 – Versatile...

  • Measurement device for active and reactive power for individual machines/feeders
