PQube 3 Instruction Manual
2 Introduction
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).

PQube 3 Instruction Manual
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.

PQube 3 Instruction Manual
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?

on the mains connections. This device must be clearly marked as the disconnecting device for your
PQube 3, and must be marked to indicate the disconnection function. Do not install your PQube 3
in such a way that it becomes difficult to operate this disconnecting device. The disconnecting
device must not disconnect the earth connection. The disconnecting device should be installed
near your PQube 3, within easy reach of the operator.
3.1.4 Protect the operator from the hazardous terminals
IMPORTANT: All high voltage parts must be covered, including the AC power to your PQube 3.
Install your PQube 3 so that all of the screw terminal blocks are not ACCESSIBLE1 to the operator.
Your PQube 3 can also be installed without a cover if installed in a lockable IUL 508 control panel.

PQube 3 Instruction Manual
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 terminals 3.1.5.1
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 Module 3.1.5.3
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 Module 3.1.5.4
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 Ratings 3.1.5.5
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.

PQube 3 Instruction Manual
A note on choosing the appropriate range of CT’s for your application:
peak currents.
3.1.11 Installing Current Transformers (CTs)
Your PQube 3 records AC current by measuring the secondary circuit of a current transformer (CT).
When installing current transformers, it is important to match the phases to the voltage inputs and
current input (connect the L1 voltage input and the L1 current sensor to the same conductor). This
is necessary for correct power and energy calculations.
Instructions for setting your CT ratio can be found on page 38.
IMPORTANT: You must only use UL listed energy monitoring current transformers with your
PQube 3.
If the PQube 3 is installed to monitor power and load, the nominal rated
current of the CT should be the most common load current throughout the
consumption period (e.g. work days). Your PQube 3 makes current
measurements with a Crest Factor of 3.5. This means that your PQube 3 can
measure instantaneous currents up to 350% of the nominal rated current (for
example, if you have selected a 300-amp current transformer, your PQube 3
will accurately measure up to ±1050 amps instantaneous). This is a very
useful feature when dealing with inrush currents, and currents with high
harmonic contents.
If the PQube 3 is installed to troubleshoot circuit breaker trip operation, the
nominal rated current should be selected closer to the trip settings. In all
cases the PQube crest factor of 3.5 provides a margin to capture properly the
PSL Ultra-Precise CTs 3.1.11.1
PSL Ultra-Precise CTs are specifically designed for your PQube 3. They are calibrated
to match the input impedance of your PQube 3’s current input channels, and each
CT comes with its own NIST-Traceable calibration certificate and table which you
can upload to your PQube 3. This is important if you need to measure high-order
current harmonics or if you need revenue-grade accuracy for your application.
PSL Ultra-Precise CTs are UL listed and utilize a 0.333V secondary to match your
PQube 3’s current input terminals. A burden resistor is built into the CT so you do
not need to worry about hazardous open circuit voltages.
You can see the list of available PSL Ultra-Precise CTs for your PQube 3 here:

Installing CTs with 0.333V secondary 3.1.11.2
Your PQube 3 comes standard with 8 current input channels, which are typically used to measure
L1, L2, L3, N, E, plus 3 additional single-phase channels. The current channels on your PQube 3 are
rated for 0.333V nominal input, and they are designed to be used with CTs with 0.333V secondary.
For PSL CTs, white wires are positive and black wires are
negative.
If using PSL Ultra-Precise CTs with the shielded secondary
wires, red is positive and black is negative. Connect the shield
conductor to ground. If using another manufacturer’s CTs,
verify which wires are positive and negative before installing
them.
Clamp the CT around the conductor. For all PSL CTs, the label faces towards the source.

1A or 5A vs. 0.333V secondary, what’s the difference?
Installing CTs with 1A or 5A secondary 3.1.11.3
If you will be monitoring the 1A or 5A secondary of existing metering CTs, you will need to use the CTI1A or the CTI-5A module. They have 1A and 5A nominal inputs, respectively.
The CTI module inputs are installed in series with your 1A or 5A secondary circuit. The terminal block on
your CTI module is connected to the 0.333V current input channels on your PQube 3. Each CTI module
includes 4 current channels, so you can use up to 2 CTI modules per PQube 3.
WARNING: When installing CTs with 1A or 5A secondaries, take extra precautions to ensure that an
open circuit does not develop on the secondary wires. Shorting blocks are typically used to avoid the
possibility of an open circuit during installation. CTs must be installed only by an qualified personnel for
electrical installations.
Most current transformers are designed to have 1A or 5A of current flowing
through the secondary circuit while full rated current is flowing through the
primary circuit.
While installing CTs with 1A or 5A secondary, it is imperative that an open
circuit does not develop in the secondary. If an open circuit develops while
current is flowing through the primary of the CT, a very hazardous open
circuit voltage (OCV) will develop across the opening. In this condition,
typical OCV values can range from hundreds to thousands of volts.
For this reason, PSL offers CTs exclusively with 0.333V secondary. Our CTs
include a built-in burden resistor in the secondary circuit so that the current
always has a path to flow through. The resistor value is calibrated and tuned
to achieve a 0.333V drop across the resistor at full rated current. This 0.333V
signal can then be measured using the 2 wires coming out of the CT.
