EMC Test Report
Reference No.: NK2GE 642.EMS
12. Fast Transients/Burst (EN 61000-4-4)
12.1 Test criteria and test procedure
Operating environment;
Temperature:
20 ℃
Relative Humidity:
40 %
A ground reference plane was located on the floor, and connected to earth via a low impedance connection.
The EFT/Burst generator's reference ground was connected to the reference plane. In case of a floor
a floor standing equipment, EUT was placed on the reference plane on 10cm of insulating support.
In case of table-top equipment, EUT was placed on a wooden table 0.8m above the reference plane.
Burst were fired at ±1kV to each single line at the AC and DC mains, and ±0.5kV was applied to signal
cables using a capacitive coupling clamp.
