  • Scalable PQ measurement system for up to 10 outputs, can be installed without shutting down the system
  • Scalable PQ measurement system for up to 10 outputs, can be installed without shutting down the system
  • Scalable PQ measurement system for up to 10 outputs, can be installed without shutting down the system

The LINAX® PQ5000CL enables certified power quality and performance analysis with up to 32 conductors in low-voltage sub-distribution. Current Link technology is used to centrally record current values via a measuring device; the Rogowski sensors are networked in a scalable ring circuit. This reduces installation costs and ensures neat cable routing. The system is metrologically certified and complies with the standards IEC 60688 (transducer), IEC 61557-12 (power metering), and IEC 62586-1 (power quality).
