Harmonics & Flicker Test Solutions

1-ECTS2-Collage_sm.pngPacific Power Source has a rich history of providing Harmonics & Flicker and Avionics test solutions to perform compliance testing to both Commercial (IEC) and Avionics (RTCA, Mil-Std, Boeing, and Airbus) test standards. 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 systems. These Harmonics & Flicker  Test systems are named ECTS2 for “EMC Compliance Test Systems, gen 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 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 both power line Emissions per IEC 61000-3-nn standards and power line immunity per IEC 61000-4-nn standards.

Power line emission standards are commonly referred to as Harmonics & Flicker and covers single and three phase products drawing up to 75A per phase.

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.

Pacific Power Source offers and extensive range of IEC 61000-3 AC Emissions test solutions and pre-programmed IEC 61000-4 AC (and DC) Immunity test sequences. Specifically, the following IEC test standards are supported:
