3.15. Voltage Dips and Short Interruptions: IEC 61000-4-11(2004)
EN 55024 specifies the IEC 61000-4-11 Standard as the basic standard for voltage variations immunity
testing. This standard relates to the immunity requirements, test methods, and range of recommended test
levels for immunity to variations in AC line voltage. The standard configuration as outlined in the IEC
61000-4-11(2004) was used. The EUT is powered up to a nominal voltage of 230 VAC 50 Hz, and then
software-controlled voltage dips and interruptions are introduced. The EUT is tested with a > 95% reduction
for 0.5 periods, repeated once per minute for 3 repetitions. Next the dip is changed to a 30% reduction for 25
periods with the same rate for 3 repetitions. Finally a voltage interruption is performed with a >95%
reduction for 250 periods. This is also repeated 3 times at 1-minute intervals.
For further information, please refer to the technical sections of the IEC 61000-4-11(2004) Standard in
addition to the test results section and photographs of the test set-up provided in this report.
