Multiple load power quality monitoring

PQube 3e monitors up to four 3-phase circuits. It replaces four traditional revenue-grade meters in addition to providing advanced power quality monitoring. You also get environmental sensing, and external process measurements, with the same ultra-precise results, delivered immediately to your inbox.


Multiple load power quality monitoring, used in a broad variety of industries: semiconductor, medical imaging, telecommunications, HVAC, pharmaceutical manufacturing, transportation (ships, aircraft, trains, electric vehicles), electrical power (generation, distribution, solar, wind), government and university research, military, etc.


  • Computes 4-quadrant ANSI Class 0.2 revenue–grade energy on 14 single-phase energy metering channels – 4 three-phase loads, 14 single-phase loads or any combination
  • Flexible assignment of voltage channels 
  • User-definable demand intervals (3 mins to 30 mins)
  • Quantify energy costs with revenue-grade-accuracy (ANSI Class 0.2 including CTs)
  • Synchronize peak current events on all 14 channels
  • Accurately analyze renewable and distributed generation system behavior
  • Verify the quality of power supplied by the utility, and any transfer to redundant sources
  • Monitor and measure potentially damaging high-frequency transients
  • Narrow down the root cause of a facility shutdown, equipment failure, or product quality issues
  • Use historical vs. present data to predict potential equipment failure
  • Easy to install with an ultra-compact footprint 
  • Connects directly to voltages up to 690 V
  • Certified for Class A power quality according to IEC 61000-4-30 Ed3
  • Monitors DC power and process parameters with four additional AC/DC analog channels 
  • Detects and records high-frequency impulses at 4 MHz
  • Measures in real time and records 2 kHz ~ 150 kHz emissions 
  • Auto-detects the mains frequency, wiring configuration, and nominal voltage
  • Holds years of data and events
