EN/IEC 61000-4-5 EMC Surge Immunity Test, Setup, Equipment
The mother of all tests! Injecting a lightning strike event, scaled down to meet your DUT at a suitable injection point. In order to determine how to reproducible this particular electromagnetic event, a brave engineer stood out in the rain for days until he captured lightning in a bottle. Because of the long life span of a lightning event, the engineer was able to take it home and analyze it’s electrical characteristics. Bring forth the birth of the 1.2/50 voltage, 8/20 current, combination waveform. True Story!
IEC 61000-4-5 TestingMost current surge immunity generators for commercial products are fairly straightforward and easy to use. With adapters that allow you to plug a power cord into the wall, and your DUT into the coupling network (on the front). At least read the first couple pages of the manual! Safety instructions include proper grounding, and what not to touch or where to be when the test sequence initiates.
- Surge Immunity Generator
- Coupling/Decoupling Networks
- Isolations Transformers
- Ground Reference Plane
- Calibration Kit (Optional)
- EMI Shielded Room (Optional)
Why Test to IEC 61000-4-5'Cause you just failed at the test lab? Just kidding...While you've properly shielded your sexy new products electronics in a housing deemed resistant to electromagnetic fields. With the increasingly crowded world of electronics, your product is likely going to be subjected to electromagnetic fields that are coupled on to power or data lines. Injecting RF noise onto these lines will allow you to test and measure the performance of your DUT.
- Identify EUT and associated equipment
- Place Generator close to EUT
- Determine test sequence and levels
- Determine ports to apply surges
- Apply 5 Surges in 1 minute intervals
- Determine EUT performance
- The recovery time of the EUT if necessary
