2Introduction
2.1 What is a PQube® 3?
Your PQube® 3 is an instrument for monitoring electric power systems and environmental
conditions, designed to help you solve problems that impact the quality and reliability of your
product or process.
Think of it as a black box for your electric power and environment. It is a combination of a power
disturbance monitor, a power/energy meter, a data logger, and a digital fault recorder –it
combines the best features of all four. It’s easy to use, too. Just transfer the data to your
computer using a standard flash device like a USB drive or SD card, like you would with a digital
camera. No special training is needed to operate your PQube 3.
2.1.1 What does my PQube 3 record?
Your PQube 3 records disturbances on the mains circuit: sags/dips, swells, interruptions, frequency
variations, impulses, and waveform snapshots. It also records power quality parameters like
flicker, unbalance, THD and harmonics.
Your PQube 3 also generates daily, weekly, and monthly trends/statistics reports automatically!
When equipped with compatible current transformers, your PQube 3 also records current
waveforms, RMS amps, power and carbon. It measures watts, watt-hours, VAR’s, power factor,
and other power-related parameters.
It includes channels for measuring auxiliary voltages –typically 24V AC or 48V DC.
It also has a general-purpose digital input, which you can toggle with switch contacts or a logic
signal, and a relay contact output, which opens for at least 3 seconds whenever your PQube 3
detects an event.
Your PQube 3 also measures and triggers on temperature, humidity and pressure at up to two
locations, using optional ENV1 environmental probes using the USB ports under the Ethernet port.
2.1.2 What kind of software do I need?
You don’t need special software to use your PQube 3. It records all
data on internal memory plus a removable microSD card, which can
be read by any computer.
No special software is required –just open the GIF picture files with
standard image programs, or even Microsoft Word® and Microsoft
PowerPoint®, or open the CSV files with any spreadsheet program
such as Microsoft Excel® (or OpenOffice.org Calc if you prefer
something free).
Configure your PQube 3 with our free PQube Configurator program,
or by editing a text file.

2.1.3 Which configurations are supported?
Your PQube 3 can monitor circuits anywhere in the world (single-phase all the way up to 3-phase).
It supports nominal voltages up to 960VAC phase-to-phase (600 VAC phase-to-earth) and mains
frequencies of 16.7 Hz, 50 Hz, 60 Hz, and 400* Hz. For medium and high voltage applications, your
PQube 3 supports PT and CT ratios up to 50000:1.
Your PQube 3 can also be used to monitor DC voltage, which can be useful for solar applications
(monitor the AC and DC voltages of your inverter).

2.1.4 How do I power my PQube 3?
It can be directly powered from 24V AC or 24~48V DC or Power over Ethernet (PoE), or it can be
equipped with an optional snap-in PM1 Module that operates from AC 100V ~ 240V, 50/60/400
Hz. You can also apply DC 120V ~ 370V too!
2.1.5 How do I communicate with my PQube 3?
No network is required to retrieve files from your PQube 3. Simply copy the data to your computer
using a USB thumb drive or microSD card.
If you have a network connection available, your PQube 3 can automatically send you e-mails
whenever it detects an event. You can send your PQube 3 a new setup file, or even update its
firmware via e-mail. It also includes a built-in web server, FTP server, and supports communication
protocols including MODBUS TCP/IP, SNMP and more, giving you many ways to communicate with
your PQube 3.

2.2 How Is Your PQube 3 Different?
There are many power quality meters, energy meters, and energy recorders available. What
makes the PQube 3 stand out from other products?
No software. No rental fees. Open data. -- You don’t need any software from PSL to use
the PQube 3. Do you have a web browser? A text editor? A spreadsheet program like
Microsoft Excel®? That’s all you need! All the data that the PQube 3 records are in open
formats that are easy to understand. You don’t have to buy or lease software from Power
Sensors Ltd, you don’t have to pay us to see your data, and the files are easy to pass on to
third parties.
Friendly data. –When you need information about your electric power, you don’t have
time to learn how to use complex software to get the view that you want. You simply
want your data organized and presented to you in a format you can understand. Your
PQube 3 presents power quality events and trends in formats you can easily use and lays
the data out in a way that’s understandable. Your PQube 3 knows what’s important.
Works out of the box, or configure everything to work for you –With our patent-pending
auto configuration, you can connect your PQube 3 to the power that you want to measure
and the PQube 3 will immediately start recording data. If you don’t like the default
settings you can change almost any setting using the PQube 3 Configurator program, or by
editing a text file on the SD card.
Works with or without a network –Do you have an Ethernet network? Plug the cable
into your PQube 3’s Ethernet port and get emails when an event occurs, browse the
recorded events and trends with your web browser, integrate it into your Modbus system,
or send traps to your SNMP server. Don’t have a network? No problem, just walk up to
the PQube 3 and extract the data onto a USB thumb drive. You can look at all the files on
any computer (you don’t need proprietary software). You don’t need a sophisticated
centralized data collection system to get started. Just connect a PQube 3 and start getting
data right away.
Store years of data on standard SD cards. –Your PQube 3 comes with an 8GB microSD
card which can hold up to 1 year of data under normal conditions. It automatically deletes
the oldest data when it becomes full, so no maintenance is required!
Small size –The PQube 3 is tiny (a little bit bigger than your fist), and that makes it easier
to integrate into your equipment, enclosure, or electrical panel.
Great value –At Power Sensors Ltd, we’re experts at building power sensor electronics.
We know how to do it right, and we know how to do it inexpensively. The PQube 3
provides high-end features at an affordable price.
It’s everything you need. –Power quality data: dips, swells, frequency variations, rapid
voltage changes, voltage and current harmonics, high frequency emissions and high
frequency impulses. Energy data: kWh, kVAh, kVARh, and carbon. Trend data: daily,
weekly, and monthly strip charts, cumulative probability and load duration. Why buy
multiple meters when your PQube 3 can do it all?
