IEC 61000-4-11:2004 Electromagnetic compatibility (EMC) - Part 4-11: Testing and measurement techniques - Voltage dips, short interruptions and voltage variations 

IEC 61000-4-11:2004 Electromagnetic compatibility (EMC) - Part 4-11: Testing and measurement techniques - Voltage dips, short interruptions and voltage variations 

EN IEC 61000-4-11 sets the immunity test methods and range for equipment connected to low-voltage power supply networks for voltage dips, short interruptions, and voltage variations. It covers equipment not above 16A/phase for connection to 50 or 60 Hz A.C. EN IEC 61000-4-11 falls into the greater structure of EN IEC 61000 which covers broader EMC concepts. Voltage dips and short interruptions are caused by faults in the network, primarily short circuits, in installations or by sudden large changes of load. In certain cases, two or more consecutive dips or interruptions may occur. Voltage variations are caused by continuously varying loads connected to the network against a certain benchmark. This standard can be purchased at the IEC WebstoreEN IEC 61000-4-11 Dips & Interruption Waveform
EN IEC 61000-4-11 standard categorizes three levels of testing and can be verified by Dips and Interrupts EMC Test Equipment. The three different classes are defined further in the standard allowing testing to be conducted accordingly. This standard does not define testing with pass/fail criteria but on performance criterion, similar to that of other IEC standards.This standard does not cover equipment for connection to 400 Hz A.C. EN IEC 61000-4-11 places regulation on the environment, limits, testing and measurement techniques, installation and mitigation guidelines, and many other criteria.  

Voltage Dips Level 61000-4-11

EN IEC 61000-4-11 sets the requirements for EMC test equipment to test for voltage dips, short interruptions, and voltage variations. It specifies preventing the emissions of heavy disturbances on power supply and providing voltage dip equal or more severe then required by the standard. We offer rental products by Teseq, EMC Partner, EM Test, and Thermo-Keytek. We also provide a variety of rental accessories for our equipment allowing customers to meet a variety of requirements. The most commonly rented equipment to simulator this event are the Profline, NSG 3060, UCS500n7, TRA3000, and EMC Pro. These EMI dips and interrupts products come with an A2LA accredited calibration and free technical support included with the rental.

EN IEC 61000-4-11 - Dips & Interruptions Immunity


Thermo Keytek ECAT E103, EP62 - Dips and Interrupts EMC Immunity Testing per IEC 61000-4-11

Thermo Keytek ECATS with the EP 62 voltage variations module for single phase 277V, 32A equipment per IEC61000-4-11


ECAT EP62 Rent & Buy Used - Thermo Fisher/Keytek Dips & Interrupts IEC 61000-4-11

The ECAT EP62 made by Thermo Fisher Scientific / Keytek is designed to provide swells, dips, and interrupts(PQF) on power mains up to 240v and 32a. This Thermo Fisher Scientific EMI immunity test equipment comes with an  A2LA accredited calibration included with rental or purchase. The EP 62 plug-in module requires the ECAT E103 control unit.

This Thermo Fisher Scientific / Keyte test equipment provides single port testing and allows changing tests modes without switching off power to the equipment under test (EUT). This helps testing with the EP62 be conducted efficiently without re-initializing the EUT between tests. This unit can be easily integrated with preexisting ECAT system by sliding the EP62 into open bay of the ECAT E103 control unit.

The ECAT EP62 is designed to test EN IEC 61000-4-11 and is compliant to single phase of this EMI Immunity standard. The modular system provides the ability to be upgraded providing the ability to upgrade test capabilities to meet the newest standard. The EP62 is a cost effective solution and in excellent working conduction and software can be acquired with purchase.
