10. Voltage Dips & Interruptions
Test
Requirement(s):
EN 61000-4-11: 1994
(A1:2001)
Test Engineer(s): None
Test Results: None Test Date(s): None
Test Procedures:
A Voltage Dip and Voltage Interruption Immunity test was performed using the mode of operation and
configuration noted within this report. The standard applies to electrical and electronic equipment
having a rated input current not exceeding 16 A per phase. It does not apply to electrical and electronic
equipment for connection to D.C. networks or 400 Hz A.C. networks. Electrical and electronic
equipment may be affected by voltage dips, short interruptions or voltage variations of power supply.
Voltage dips and short interruptions are caused by faults in the network, in installations or by a sudden
large change of load. In certain cases, two or more consecutive dips or interruptions may occur. The
continuously varying loads connected to the network cause voltage variations.
In cases where both 230 VAC and 120 VAC tests are performed, the 5 second voltage drop out will only
be performed on the 230 VAC test run.
