The EMC Shop stocks testing equipment to certify and comply to EN/IEC 61000-4-29: DC Drops, Dips & Interruptions Immunity Testing.

OVERVIEW OF IEC 61000-4-29

The operation of electrical and electronic equipment can be affected by voltage dips, short interruptions or voltage variations of the supply. Voltage dips and short interruptions are mainly caused by faults in the DC distribution system or by sudden changes of large loads. Voltage variations are primarily caused by the switching of mechanical relays when changing from one source to another (e.g., from generator set to battery).

Rise and fall time of the voltage change, generator loaded with 100 Ω resistive load: Between 1 µs and 50 µs.
