The PQube power quality analyzer is a tiny, user-friendly power quality recorder with built-in power, energy, and carbon emissions monitoring. With the PQube, there is no software required - all recorded data is written directly onto an SD memory card in a number of ready-to-use formats including HTML web pages, spreadsheets (Excel-compatible CSV files), pictures (GIF images, eg for power/energy trends and waveforms on power quality events), text, XML and PQDIF (the IEEE standard for power quality data files.)
Key Features
- Three-phase and single-phase monitoring up to 690V, 50/60/400Hz.
- Auto power configuration (patent pending).
- Power Quality monitoring: “Your PQube is like the black box on an aircraft: if anything goes wrong with the power, it records all the details.”
- Voltage dips, swells, and interruptions – waveforms and RMS graphs.
- Over-frequency and under-frequency events.
- 1-microsecond high-frequency impulse detection.
- THD, TDD, and time-triggered snapshots.
- Voltage and current unbalance.
- RMS Flicker – Pinst, PST, PLT.
- Detailed event recording, plus daily, weekly, monthly trends. Cumulative probability, histograms, and more.
- Energy monitoring: “The most accurate little monitor on the market. Complete energy information.”
- Watts, VA, VAR’s, true Power Factor, Watt-hours, VA-hours.
- Daily and accumulated CO2, and CO2 rate (patent pending).
- Peaks: single-cycle peak, 1-minute, and 15-minute averages.
- CT ratios support up to 50,000 amps . PT ratios support up to 6,900,000 volts.
- Daily, weekly, monthly trends. Load duration curves and more.
- No software required! The PQube automatically writes these files on a standard digital camera SD card:
- Spreadsheets: CSV Excel®-compatible files; events, trends, statistics.
- Pictures: Event and trend/statistics graphs – dual-language picture graphs output directly from PQube in typical GIF format
- PQDIF (beta): the IEEE’s standard for power quality data files.
- Text, XML, and HTML summaries: perfect for interfacing with other programs.
- Easy data retrieval:
- Sneakernet: Pop out SD card, just like a digital camera, and copy files to your PC.
- Ethernet:
- Email for easy approval by IT department. Automatically sends you events, trends, and statistics in the language of your choice.
- Built-in web server – retrieve meters, files, and more.
- FTP server for easy file transfer (beta).
- Modbus-TCP (beta).
- Additional channels: two analog inputs, one digital input, one relay output, and two temperature-humidity monitoring channels.
- 256 samples-per-cycle measurements on all channels.
- About 1 gigabyte per year of data. PQube comes standard with 2-gigabyte SD-card for data storage. Can use 8-gigabyte SD cards.
- Full color display. 25+ languages, date/time setup, recent events, meters, and more.
- DIN-rail or panel mount.
- Built-in Li-Ion UPS. Power from 24 VAC, 24-48VDC, or optional 100~240 VAC power supply.
- FREE individual NIST calibration certificate for every PQube!
Additional Modules
There are a number of additional plug-in modules available for the PQube that increase it's capabilities.
| PS1 AC Power Supply - enables the PQube to be powered by 100~240V AC power
| 
| XCT4 Current Transformer Module - enables the PQube to monitor current so that power quality events on current can be detected. Also enables power/energy parameters to be measured. Choose this module where external 5A CTs are to be used.
| 
| CT4 Current Sensing Module - enables the PQube to monitor current so that power quality events on current can be detected.Choose this module where 5A secondary CTs are already installed. | 
| ETH1 Ethernet Module - enables network communications (LAN/WAN/Internet) are required for remote access to the meter. Includes built-in automated emails, web server and FTP server. | 
| TH1 Temperature & Humidity Module - enables up to two channels of temperature/RH to be monitored |

We are exceedingly impressed with our first experience with Optimum Energy. Not only did your group pull a rabbit out of your hat by getting us our order in less than 24 hrs, but we were given a courtesy phone call from our sales rep to make sure that we received our order. We will definitely, and happily, be doing business with Optimum Energy again.
