Product Details

The ProQ 100 is a wall mounted energy meter that monitors the power quality events of HV, MV, and LV4 configurations. The unit offers high precision revenue metering that is in line with the latest power quality standards. With multiple communication channels, protocol support, and upgrades for existing applications, the ProQ 100 can easily integrate with multiple systems that allow for concurrent communications.

Secure's innovative web-based software provides a breakdown of the ProQ100's Power Quality and Energy parameters. All electrical parameters are available in real-time with additional graphical, tabular, and ITIC Report formats for analysis.


  • Accuracy: Class 0.2S IEC 62053-22
  • Real-time data monitoring for reports, trends, and harmonic analysis through Secures online platform
  • Power Quality Event logging for sag, swell, interruption and rapid voltage change
  • Distortion factors THD, TDD, and waveform quality indices e.g. K factor and crest factor
  • Voltage and current recording for pre- and post- event analysis with RMS value (half-cycle) capture
