Voltage fluctuation (Flicker) standard EN61000-3-3 (IEC61000-3-3)
Those models which fall within the scope of EN61000-3-3, as stated in the Declaration of Conformity, conform to the
requirements for manual switching, i.e. the voltage dip caused when a drive at room temperature is switched on is within the
permitted limits.
The drive does not of itself cause periodic voltage fluctuation in normal operation. The installer must ensure that the control of
the drive is such that periodic fluctuations in supply current do not infringe the flicker requirements where applicable. Note
that large periodic load fluctuations in the frequency range of between 1Hz and 30Hz are particularly inclined to cause
irritating lighting flicker and are subject to stringent limits under EN61000-3-3.
