Overview
EN/IEC 61000-4-5 - 2014 relates to immunity requirements for unidirectional surges caused by over-voltages from switching and lightning transients. This standard defines ranges of test levels, test equipment, test setups, and test procedures for equipment under test (EUT). The goal of this International Electrotechnical Commission (IEC) standard is a reproducible guide to evaluate equipment when exposed to this type of phenomena. It specifies that direct injections of lightning currents (direct lightning strikes) are not considered in this standard. The most recent 2014 version 3 cancels out previous publications and gives specifications for 10/700 µs combined wave generator. The most changes from version 2 fall underneath the test procedures section of the standard. This Standard can be purchased on the IEC Webstore.
Testing
This IEC standard is based on a surge, a transient wave of electrical current, and is tested for by Immunity Test Equipment. This standard defines two Combination Wave pulses (Open Circuit Voltage and Short Circuit Current). It set the number of pulses from the EMC test equipment to a.c. ports, d.c. ports, and interconnection lines, at 5 positive and 5 negative (a.c. at 0°, 90°, 180°, & 270°). The time per each pulse must be one minute or less and the EUT must be under operating conditions while the EMC testing is occurring.
Generators
For EN/IEC 61000-4-5 combination wave/surge rentals we offer a variety of different EMI test equipment suppliers including Teseq, EMC Partner, EM Test, Haefely, and many others to meet customer requirements and preferences. These products all have the capability to meet the surge requirements and each have unique testing and reporting capabilities. The most common rental units for surge testing are the NSG 3060, Axos 8, NX5, and UCS500n7. We also provide many accessories that may be required to complete unique and specific testing requirements. These EMI surge products come with an A2LA accredited calibration and free technical support included with the rental.
