IEC 61000-4-11 / -4-13 / -4-14
IEC 61000 AC Immunity Testing
AC source with 500 A peak inrush drive, 1–5 µs dip edges, phase-of-dip control, and full per-phase arbitrary waveform synthesis with independent harmonic and interharmonic amplitude and phase control.
This standard turns on
- voltage dips and interruptions
- inrush drive capability
- harmonic and interharmonic synthesis
And says nothing about
- 400 Hz
- DC bus transients
- reliability duration testing
