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.

CDN 3425 Rental - Teseq Burst/EFT Coupling Clamp

The Teseq CDN3425 (Teseq CCL) main purpose is to couple Burst/EFT pulses to data lines. It can also be used to couple to mains lines where no CDN is available; for example, high current lines >200 A. A2LA accredited calibration is included in the EMC rental equipment price.

The new design is fully compliant with the specifications of IEC 61000-4-4 Ed 2.0 2004, as well as with the draft of EN/IEC 61000-4-4 Ed 3.0 to be published in 2012.This model also replaces earlier models CDN 8014 and CDN 8015.The coupling capacitance between the coupling clamp and the cable laid in it depends on the cable characteristics. 


EOS1 Rental - Electronic Switch For EN IEC 61000-4-11 with the Profline Test System

The EOS 1 by California Instruments is an electronic output switch provides full AC source compliance for dips and Interrupts testings. There are many ways to test a product to verify immunity from line variations, and some form of standardization, for comparison purposes, is desirable. A2LA accredited calibration is included in the EMC rental equipment price. 

The standard, EN/IEC 61000-4-11, seeks to specify the parametric requirements of an AC source suitable for performing the specified tests. Generally, these requirements go beyond what is necessary on a particular product.


DIP 116 Haefely Automatic Dips Single Phase Transformer at 40/70/80%

The DIP116 by Haefely Hipotronics (in conjunction with Axos5 & Axos8) is an automatic dips single phase transformer and can be used to simulate power supply failures as Voltage Dips and Interrupts at 0/40/70/80[%] of AC Voltage input. A2LA accredited calibration is included in the EMC rental equipment price.

This Dips and Interrupts tester is designed as an accessory that is compatible with the AXOS series (Axos 5 & Axos 8). This product requires an individual connection to an outside power source. Following the setup with related Axos product it can via the menu option of "Voltage Dips".

The DIP 116 is compliant to EN/IEC 61000-4-11.Voltage dips and short interruptions are caused by faults in the network. These are primarily short circuits in installations or by sudden, large changes in load. In certain cases, two or more consecutive dips or interruptions may occur.


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


V4780 S2 Rental - EM Test External Variac For Dips And Interrupts Testing With The UCS 500n Generators

EMTest automated external transformer for the UCS 500n7 and UCS 500n5 generators to perform the dips and interrupts test for EN IEC 61000-4-11.


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.
