PQube 3

This compact instrument is simply the best power monitor and real-time sensor you can buy.

It records every type of AC power disturbance – including 4 MHz sampling of impulses – and it is an IEC 61000-4-30, edition 3 Class A certified, ultra-precise revenue-grade energy meter. Monitor up to two three-phase loads, or eight single-phase loads with a single instrument.

It goes beyond AC power too. Records environmental data – such as temperature, humidity and barometric pressure, vibration, 3-axis acceleration – as well as process parameters, including torque, RPM, fuel level, water flow, and more.

Easy to install, easy to use! Delivers ultra-precise results immediately to your inbox.

Testimonials

PSL Team,
Thank you for introducing us to PQube 3. It has saved us a tremendous amount of time and manpower as far as troubleshooting goes. I’m able to see any power abnormalities right-away from my desk-top or mobile device and dispatch the correct response personnel if needed. This has saved us money by allowing us to get ahead of several electrical problems before they became major issues at our water and sewer treatment plant. Since we have so much equipment to maintain, the ability to receive real-time data is extremely comforting to us as well. We are extremely satisfied with PQube 3 and will continue to use it going forward.

PQube 3 delivers information that you can use immediately

  • Monitors AC power (or DC power),  but also your process parameter like speed or flow, with additional  analog AC/DC channels
  • 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 (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 3 installs easily

  • 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 its configuration

PQube 3 is easy to use

  • 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

MULTI-CIRCUIT, REVENUE-GRADE ACCURATE ENERGY METER

  • Easily connects current channels with split-core CTs or Flexible (Rogowsky coils) CTs
  • Supports 8 X single phase circuit or 2 X 3-phase circuits
  • Complies with ANSI C12.20 Class 0.2 revenue grade accuracy (*)
  • Computes 4-quadrant energy (import/export, reactive/capacitive)
  • Computes active/reactive/apparent powers, Power Factor or DPF (CosPhi)
  • Supports user-defined demand intervals (3, 10, 15, 30, 60 mins)
  • Publishes real-time values of all powers and energies (Modbus TCP/IP)

(*) Class 0.2S  IEC 62053-22, too! 

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 PQube3 four analog AC/DC channels
  • Detect and record mechanical shocks, seismic disturbances, tilt changes

PQube 3 HAS THE BEST POWER QUALITY AND POWER ANALYZER SPECS

  • Synchronized sampling at 512 sample per cycle on ALL channels
    (includes eight currents, four AC/DC analog, one digital)
  • Up to 4 MHz(*) high frequency impulse detection and recording, on all four voltage channels
  • Fully compliant with Class A requirements of the measurement method IEC 61000-4-30 Ed3
  • Sags/swells/interruptions on mains voltage, (IEC 61000-4-30 Ed3 /IEEE 519), also on analog AC/DC channels
  • Voltage, current harmonics and inter-harmonics according to IEC 61000-4-7
  • Voltage Flicker Class F1 according to IEC 61000-4-15
  • 2 kHz-150 kHz conducted emissions according to IEC 61000-4-30 ed3  (real time and recorded)
  • Monitoring of 2 X 3-phase voltage synchronized measurements (dual mode)
  • Clock synchronization via NTP, SNTP, or GPS
  • Waveform recordings up to 128 cycles, and up to 16 seconds RMS, upon event occurrence
  • Months of measurement data (16 GB embedded flash memory)
  • Embedded Web server, FTP server, email server, and embedded firewall
