Pacific Power Source has a rich history of providing Harmonics & Flicker and Power Line Immunity test solutions. With a large installed base of precision AC Power Sources in both commercial and defense related accounts, we offer a broad spectrum of software and hardware solutions that help our customers accomplish compliance with regulatory product requirements.
More recently, Pacific Power has developed a turn-key line of IEC Compliance power line emissions and immunity test system. These Harmonics & Flicker Test systems are called ECTS2 for “EMC Compliance Test Systems, generation 2”. ECTS2 Systems come in a range of power levels and output phase configurations and are all based on Pacific Power programmable AC and or AC+DC power sources and our Harmonics and Flicker Measurement and Flicker Reference Impedance modules. For details visit our ECTS2 Series product page.
IEC Power Line Immunity Compliance Test
The EMC Directive is one of the ‘New Approach’ Directives and applies across all 27 member states of the European Union (EU). The Directive applies to all electronic or electrical products liable to cause or be disturbed by electromagnetic interference (EMI). As a result a large number of manufacturers in the electronics or electrical industries need to ensure that their products are compliant with the requirements of the Directive and be able to demonstrate that this is the case in order to affix the CE Mark.
To verify compliance with these directives, the International Electrotechnical Commission has issued a number of harmonized standards that describe test methods, test levels and pass or fail criteria. This includes power line immunity per IEC 61000-4-nn standards.
Power line immunity test standards cover immunity to commonly found AC power line anomalies that are known to occur on the public Low Voltage (LV) network. These conducted immunity standards are numbered IEC 61000-4-nn. The IEC is one of three global sister organizations (IEC, ISO, ITU) that develop International Standards for the world.
This page provides and overview of available EMC Immunity Test Software solutions provided by Pacific Power Source to control several model series of programmable Power Source and ECTS2 EMC test systems to perform these immunity tests. These dedicated EMC Test Software solutions provide application specific user operation and EMC compliant test reports to document product compliance.
Pacific Power Source offers and extensive range of IEC 61000-4 AC (and DC) Immunity Test Windows 10 Software GUI programs. Specifically, the following three programs – Epts_Gui, Ects_413Gui and Ects_4xxGui – support the IEC test standards listed below:

EPTS Option |
* For full compliance with generator Rise and Fall times, the EPTS Option is required. |
IEC61000-4-11, IEC61000-4-27, IEC61000-4-29 & IEC61000-4-34
These three IEC Immunity test standards cover Voltage Dips, Interruptions and Variations as well as Voltage Unbalance immunity testing . The EPTS (Electronic Power Transfer Switch) unit and included EpstGui control software is used to implement all tests in these standards. This ensures the required rise and fall times for voltage dips are met as needed for full compliance testing.
The EptsGui control software captures all EUT information and allows the operator to select the desired test standard and EUT test class, then performs the required voltage immunity tests. Once completed, a detailed test report that incorporates all required information on the EUT and tests applied is generated for documentation purposes.
IEC61000-4-13
The IEC61000-4-13 Immunity test standard covers Harmonic and Interharmonic voltages and their potential effect on a EUT. The Ects_413Gui software is included with the IEC413 “C” Option on AFX, AZX and LMX Series programmable power sources.
The Ects_413Gui control software captures all EUT information and allows the operator to select the required IEC 413 tests that are part of the standard of all supported EUT test classes, then performs the required voltage immunity tests. Once completed, a detailed test report that incorporates all required information on the EUT and tests applied is generated for documentation purposes.
IEC61000-4-14, IEC61000-4-17, IEC61000-4-27p & IEC61000-4-28
The IEC61000-4xx Immunity test software (Ecst_4xxGui) support four different IEC61000-4 Immunity tests. The Ects_4xxGui software is compatible with AFX, AZX and LMX Series programmable power sources. Note that he IEC61000-4-17 test is a DC test and is not supported on the LMX Series).
The Ects_4xxGui control software captures all EUT information and allows the operator to select the required IEC61000-4-xxx test and supported EUT test classes, then performs the required voltage or frequency immunity tests. Once completed, a detailed test report that incorporates all required information on the EUT and tests applied is generated for documentation purposes.
