Full Featured AC Power
Source
Available in a choice of power levels
ranging from 1250 VA to 30,000 VA,
CTS Systems cover the complete
range of single and three phase products that need testing to conform with
existing and pending IEC standards.
All iX Series AC sources meet IEC requirements for low voltage distortion
and offer arbitrary waveform generation, precision measurements, and
waveform analysis capabilities.
All iX Series based CTS systems support full compliance IEC 61000-4 AC
immunity test as well (certain options
may be required).
The 1251RP source meets the same
requirements for low power loads with
crest factors less than three. AC
Source voltage distortion is measured
in real-time during the harmonics test
and any distortion that could affect the
test results is clearly indicated.
CTS Series - System Components
Source Control
The IEC GUI software controls the AC
power source using the IEEE-488 or
RS232C interface. Settings for nominal voltage and frequency are automatically applied and possible overload
conditions are detected and reported
to the operator. IEC 61000-4 AC immunity tests run completely under software control.
PC Bus Data Acquisition
Harmonics Analyzer
A high speed digital signal processor
based data acquisition system is used
to implement the required IEC compliance measurement system. Direct access to the PC bus ensures a much
higher data throughput capability than
typically found in single box IEC test
systems that use the IEEE-488 instrumentation bus to communicate with the
PC.
A key part of the CTS system is the
IEC compliant power analyzer which
provides detailed information on both
voltage and current harmonics. Measurements are made in real-time with
no measurement gaps to fully conform
to IEC 61000-3-2 transitory harmonics
test requirements. AC source voltage
and EUT power are monitored continuously during the entire test. Voltage distortion and current harmonic data is checked
against IEC class limits
for pass or fail detection. Comprehensive
test reports can be generated easily. Continuous measurement of
the EUT power consumption allows class
C and D test limits to be
calculated dynamically.
A special signal conditioning and isolation unit is used to provide quick and
easy connection between the AC
source output and the Equipment Under Test. This unit provides the required isolation, signal conditioning and
anti-alias filtering for the measurement
system. The equipment under test can
be plugged in the front panel mounted
European style outlet, or wired to a rear
panel mounted terminal block. An optional international socket strip with
multiple country specific outlets is available.
Test limits are retained
in a password protected
database and can be
updated if needed in the
future without the need
to change software. Other software
changes as a result of changing IEC
harmonics standard can be accomplished by simply downloading new PC
software. No harmonics testing software resides in system firmware which
would require more costly upgrades.
Flicker Meter and Impedance
An IEC 868 compliant flicker meter is
provided with the CTS software. The
required IEC 725 compliant reference
impedance is implemented in the iX
Series AC Source using programmable
output impedance. Programmable impedance offers improved accuracy
compared to a lumped reference impedance and the ability to support different national standards without the
need to switch out lumped reference
impedance hardware. A good example
is testing for compliance with the Japanese harmonics and flicker standard,
which requires different impedance
values to be programmed from the
European test standard.
Optionally, a lumped impedance compliant with IEC 725 can be ordered for
both single and three phase iX Series
based CTS systems. The GUI software can be configured to use either
impedance type during flicker testing.
The three phase lumped impedance
option (-LR3) for the 15003iX-CTS system is shown here. The 30003iX-CTS
system does not support programmable impedance and requires option
-LR4 for flicker testing.
The RP-Series based CTS systems
use a lumped impedance integrated in
the PACS-1RP and PACS-1RP2.

Apparent Power and Power Factor. The current harmonics
window displays instantaneous current harmonics and a
line marking the applicable test limits. During the entire test
run, a clear PASS or FAIL indication is provided. Any conditions occurring during the test run that may affect the test
results can be displayed. This includes voltage THD of the
AC source, which is monitored during the entire test. Information about the operator and the unit under test can be
entered. A general user comment field is provided to enter
any relevant data concerning the test. All this information is
added to the final test report.
A complete IEC harmonics test report, which includes all
test results for the EUT, can be printed at the end of the
test. This report includes graphs showing voltage and current waveforms as well as current harmonic spectrum and
class limits. All graphs are included in the test report or can
be copied to the Windows® Clipboard for inclusion in custom reports. Comprehensive test data, including timing
waveform data, is available from disk for use in detailed
Available Data Displays

IEC 725 Reference Impedance
The reference impedance required to perform flicker measurements per IEC 725 is built-in to the PACS-1RP unit for
the 1251RP-CTS system or the PACS-1RP2 for the
2001RP-CTS system. All iX Series based CTS configurations use the programmable output impedance of the AC
Source to provide the required output impedance. Users
that prefer to use a lumped reference impedance can order
option -LR1 for single phase iX-Series based CTS systems
or option -LR3 or -LR4 for three phase systems.
Real-time display of instantaneous Pst
Test Reports and Data Logging
A summary IEC 61000-3-3 Flicker test report can be printed
at the end of the test which includes all test results for the
EUT. Refer to the section on IEC 61000-3-2 for report details and capabilities. A test file replay mode is supported
by the CTS system software that allows frame by frame
playback of test data files for detailed analysis of EUT behavior.
CTS Series - IEC 61000-4 Immunity Test1
iX-Series based CTS systems are supplied with additional software that allows a series of AC immunity tests to be
performed on the unit under test. Pass or Fail results are determined by the user based on an evaluation of the unit under
test at the end of the test run.
IEC 61000-4-11 Voltage Dips and Interruptions Test2
The Voltage Dips and Interruptions test are included in the
AC source control program supplied with the CTS system.
The operator is presented with a simple screen that shows
the type of test that will be run and the test duration. The
operator can enter the desired nominal test voltage and
frequency.
Clearly labeled buttons are provided for Test Run and Test
Abort. During the test run, the EUT load current is measured to help the operator observe any EUT failures.
Test parameters can be changed by the user if needed to
accommodate different test levels called out by product standard committees. For AC source compliance, the EOS option is required. This option is available on 3001iX-CTS,
5001iX-CTS and 15003iX-CTS systems.
IEC 61000-4-11 Test Window
IEC 61000-4-13 Harmonics and Interharmonics3
The iX Series AC/DC Source can be equipped with the
-413 option to provide full support for IEC 61000-4-13 Harmonics and Interharmonics testing. An independent, digitally controlled sweep generator is used to superimpose
interharmonics on the AC output. The high speed data
acquisition system is used to determine EUT resonance
points during the frequency sweep test. Flat top curve and
overswing curve waveforms are generated using the arbitrary waveform generation capability of the iX Series AC/
DC source.
At the end of the test run, a detailed test report can be
printed for complete documentation of test setup and results.

CTS Series - Report Generation
MS Word Test Reports
Test reports for harmonics, flicker and
immunity tests are generated using MS
Word format. This widely used format
report can be integrated into more
elaborate reports covering all aspects
of compliance testing if needed.
Test reports contain data on the EUT,
the test lab and operator, all measurement results and a clear pass or fail
indication. Harmonics test reports include current harmonics and voltage
harmonics data in both bar charts and
tabular formats.
Detailed measurement data is also
available on disk and can be exported
to a tab delimited ASCII text format for
use in other application programs such
as MS Excel. This allows further analysis of the acquired data for engineering troubleshooting purposes of EUT’s
that did not pass.
Note: A copy of MS Word must be installed on the PC to generate test reports.
CTS Series - PACS Specifications
The Power Analyzer and Conditioning System unit provides the required interface between the AC source, the Equipment
Under Test and the PC. Single phase CTS Systems are supplied with a PACS-1, three phase CTS systems are supplied
with a PACS-3. RP Series based CTS systems include a lumped reference impedance in the PACS-1

30003iX-CTS systems do not offer programmable impedance and require option -LR4 for Flicker test. Options -LR1
and -LR3 may be added to 3001iX-CTS / 5001iX-CTS or 15003iX-CTS configurations to be used in lieu of the
standard programmable impedance. Option -LR1 is built-in to PACS-1. Option -LR3 and -LR4 consist of OMNI-3-18i
and OMNI-3-37i respectively. See OMNI data in options section of this catalog.
CTS Series - Measurement Specifications
The following specifications are valid for
the power analyzer portion of the CTS.
PC Based A/D Conversion
The Harmonics Analyzer is implemented using a high performance Digital Signal Processor based PC plug-in
A/D card. This digitizer connects directly to the Power Analyzer and Conditioning System (PACS) unit through
a shielded cable. No other connections
between the PACS unit and the PC are
required.
The use of a fast multi-channel A/D card
that transfers data to PC memory using Direct Memory Access (DMA) enables the CTS to perform continuous
measurements without any gaps in
measured data, an important requirement for Transitory Harmonics and
flicker testing.
A choice of ISA, PCI or PCMCIA (PCCardbus) options is available to accommodate a wide range of PC platforms.
Note: PCMCIA (-MC Option) only supports single phase CTS configurations.
Signal Conditioning
The Power Analyzer and Conditioning
System (PACS) unit is used to provide
isolation between the PC based acquisition system and the Equipment Under Test (EUT). Precision current transformers provide accurate current sensing over three different current ranges
for maximum resolution. The PC based
acquisition system captures data on all
current ranges and automatically selects the appropriate range to use for
further processing. This eliminates the
need for range switching as is commonly done in conventional power analyzers.
Anti-aliasing filters are provided for all
voltage and current channels to prevent
unwanted frequency components from
affecting the measurement results.
