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).
*coming soon! Contact PSL for free firmware upgrade!
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?

to the operator.
Your PQube 3 can also be installed without a cover if installed in a lockable IUL 508 control panel.
The operator must be protected from the hazardous screw terminal blocks by a barrier. The screw terminal blocks must be made
“not ACCESSIBLE”, as defined in UL /IEC 61010-1 6.2, using an enclosure or barrier that meets the rigidity requirements of UL /IEC
61010-1 8.1 and that requires a tool to remove.

If you choose to install your PQube 3 in an enclosure, select a UL-listed enclosure that is appropriate for the purpose. If you plan
to use an enclosure of this type, you should review its mechanical compatibility with any optional features of your PQube 3 that
you plan to use: optional USB connections, optional temperature-humidity probes, etc.
Note the 1-amp, 3-phase circuit breaker, at far right, used both as external overcurrent protection and disconnecting device, near
your PQube 3.

3.1.5 Connect your PQube 3 to the power supply
Your PQube 3 can take its operating power from four different sources:
24VAC or ±24–48VDC power supply terminals on PQube 3
Power over Ethernet (PoE)
Optional PM1 Power Supply module
Rechargeable UPS module (automatically provides up to 30 minutes of battery backup
when the main power supply source drops out)
PQube 3 power supply terminals3.1.5.1
The instrument power terminals (45 and 46) on the front of your PQube 3 must be connected to
24VAC (±20%) or 24–48VDC (±20%), supplied by a certified isolating power supply.
WARNING: Applying voltages outside of this range can cause permanent damage to your PQube 3.
Polarity does not matter. Also, your PQube 3 provides a minimum of 150V of transformer-based
isolation between these terminals and all other terminals, eliminating any problems with ground
loops.
Power over Ethernet (PoE)3.1.5.2
Plug in an Ethernet cable leading to a 48V PoE source (PoE switch/hub/router or PoE injector).
If no other power sources are available, your PQube 3 will request power from the PoE switch.
If your PQube 3 is already powered from another source (24V power supply or PM1 power supply
module, for example) then it will not request power from the PoE switch when you plug it in.
UPS1 Module3.1.5.3
Plug the UPS1 module on the right side of your PQube 3 or PM1/PM2 module. This module is
always the outermost module on the right side.
By default, the UPS timer interval is 3 minutes. However, you can choose the operating duration
by writing a value in your Setup.ini file. The value can be set from 1 to 30 minutes. This guarantees
that there will be enough charge in the battery to record several successive power interruptions.

As the lithium ion battery inside the module ages, its capacity will decline. Depending on operating
conditions and requirements, it may be necessary to replace your UPS1 Module every 3 to 5 years
or 500 cycles, whichever comes first.
PM1 or PM2 Power Supply Module3.1.5.4
The PM1 or PM2 module accepts a range of 100~240VAC, 50/60/400Hz. It snaps into the right side
of your PQube 3. This module is ideal for applications where 24-48VDC, 24VAC, and PoE are not
available. Make sure your AC source can supply at least 20W.

On the PM2 module, 24VDC outputs are available on the 8-pin terminal block for powering
external accessories including DC Hall Effect sensors and indication LEDs. The first pair of terminals
labeled “Switched 24Vdc” can be toggled on and off in software. The other three pairs are tied
together internally. The total combined power output is 5W. This is enough to power one
additional PQube 3.
Maximum Load and Temperature Ratings3.1.5.5
Your PQube 3 is rated for 65°C maximum ambient temperature under normal conditions when
installed according to the procedures set forth in this manual.
However, when loading the PM2 module’s 24V auxiliary circuit with 5W, the maximum ambient
temperature is derated to 55°C.

3.1.6 Connecting the wires
Observe the wire size specifications and limitations. All conductors must be stranded copper. All
conductors and insulation systems and crimped devices must be appropriate for the application.
PSL recommends crimped ferrules on stranded wire. Tighten the screws on the high voltage
terminal block to 0,5 newton-meters (5 inch-pounds) of torque. Observe all voltage ratings and
limits.
For connections, PSL recommends wire ferrules for stranded wire, such as Panduit F77 series, for example Panduit F77-6-M.
Figure 1: Your PQube meets all IEC requirements for high-
frequency emissions and susceptibility, both conducted and
radiated. For further protection, you can use clamp-on
ferrites on signal cables to minimize radio-frequency
emissions. For example, these are Panasonic
KRCBC160928B and KRCBC130714B.
Figure 2: To minimize emissions with the optional PM1
Power Supply module, optionally use a shielded power
conductor.
