Docs: Power Quality Metering Datasheet

ResourceKraft now offers the PQube 3, simply the best power monitor and real-time sensor you can buy.


  • Monitors AC power (or DC power),  but also your process parameter like speed or flow, with additional  analog AC/DC channels
  • Integrates seamlessly with the ResourceKraft Canary Gateway unit to the Cloud based Resolve© Power Quality Analytics and Reporting system, providing an ideal solution for remote monitoring of all your PCube3's on a single platform.
  • Enhances the power diagnostic by also measuring the environment conditions with advanced EnviroSensor probes
  • Your campaign measurements are stored for years, and continuously stored as 1 min (min/max/average) trends daily, or 5 min trends, weekly or monthly. No gaps, you don’t miss a single cycle
  • You can store several thousands of events (32 GB flash memory
  • Extensive library of waveform triggers on voltage magnitude, voltage HF impulses, frequency, currents inrush , AC/DC channels, and more.
  • All measured parameters are available every half-second in real-time (via ModbusTCP/IP, DNP3.0  or SNMP)
  • Trends and events can be quickly accessed using your Internet browser – no software needed
  • Interface available in more than 13 languages– the graphs can be delivered in two simultaneous languages (ideal for international teams)

  • Connects the mains voltage directly into the PQube 3 terminals up to 600VAC nominal
  • Connects safely and quickly to currents with split-core CTs or Flexible (Rogowsky coils) CTs
  • Auto configures by auto-detecting the mains frequency, wiring configuration and nominal voltage
  • Allows easy wiring verification and provides status via the embedded color touch screen, can be operated with protection gloves.
  • Can manage connection wiring mistakes after installation is done, via configuration


  • Easy changes in configuration can be done on site with a USB thumb drive, or remotely via Web browser, FTP or email
  • Free firmware updates can be done on site with a USB thumb drive, or remotely via Web browser or FTP
