PQube 3e

PQube 3e is specifically designed for multi-load power consumption monitoring. 14 X single phase loads or up to 4 X 3-phase loads simultaneous metering within the same tiny instrument. This device provides a fast way of diagnosing power quality issues. The PQube 3e is an ultra-precise multi-function power quality and energy meter, with environmental sensing and external process measurement capabilities. You don’t need any software, PQube 3e sends you text or visualization graphics directly to you email inbox

14 Energy Metering Channels

  • 14 energy metering channels – four three-phase loads, 14 single-phase loads, or any combinations
  • Flexible assignment of voltage channels to each current
  • User-definable demand intervals (three mins up to 30 mins)
  • Four-quadrant metering:
    • Imported / exported / net active energy
    • Positive / negative / net reactive energy

Advanced Power Quality Features

  • Up to 4 MHz high frequency sampling – 250 ns transient detection and recording
  • Event-triggered recording based on sags, swells, and interruptions; over/under-frequency; waveshape changes; inrush current; and more
  • 2 kHz – 150 kHz conducted emissions recording
  • High-speed 512-samples-per-cycle recording on all channels
  • IEC 61000-4-30 Ed3 Class A:
    • Voltage sags / swells / interruptions
    • Voltage flicker (Pinst, Pst, PLT)
    • Voltage and current harmonics & inter-harmonics (up to rank 50)
    • Voltage and current unbalance
    • Voltage THD, current THD, and TDD
    • Rapid voltage changes
  • Daily, weekly, and monthly trends (with min/avg/max)
  • Daily cumulative probability, histograms, and more

MULTI-CIRCUIT, REVENUE-GRADE ACCURATE ENERGY METER

  • Easily connects current channels with split-core CTs or Flexible (Rogowsky coils) CTs
  • Supports 14 X single phase circuit or 4 X 3-phase circuits
  • Complies with ANSI C12.20 Class 0.2 revenue grade accuracy (*)
  • Computes four-quadrant energy (import/export, reactive/capacitive)
  • Computes active/reactive/apparent powers, power factor or DPF (CosPhi)
  • Supports user-defined demand intervals
  • Publishes real-time values of all powers and energies (Modbus TCP/IP)

(*) Class 0.2S IEC 62053-22

PQube 3e delivers information that can be used immediately

  • Monitors the power, but also your process with generic analog AC/DC channels
  • Enhances the diagnostic by 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 (16 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 Modbus 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)

PQube 3e is easy to manage

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

ABOVE AND BEYOND POWER MONITORING: ENVIRONMENT and PROCESS

  • Enhance your diagnostic by adding:
    • Temperature, humidity, barometric pressure, shock and sesimic measurements, vibration level with PSL’s advanced EnviroSensors (ENV2)
    • External sensors measurements, e.g. level gauges, solar irradiance, flow, speed, battery charge and consumption, with PQube 3e four analog AC/DC channels
  • Detect and record mechanical shocks, seismic disturbances, and tilt changes
