4.13. Voltage Dips and Short Interruptions: IEC 61000-4-11(2001)
This test subjects the EUT to power network faults and “brownouts”. Testing was performed in accordance
with IEC 61000-4-11. The standard configuration as outlined in the IEC 61000-4-11 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. For further information, please refer to the technical sections of the IEC 61000-4-
11 in addition to the test results section and photographs of the test set-up provided in this report.
