EN / IEC 61000-3-3
Voltage Fluctuations & Flicker
EN / IEC 61000-3-3
EN / IEC 61000-3-3 is concerned with the limitation of voltage fluctuations and flicker impressed on the public low-voltage system. SANS / This standard specifies limits of voltage changes which may be produced by equipment tested under specified conditions and gives guidance on methods of assessment.
EN / IEC 61000-3-3 is applicable to electrical and electronic equipment having an input current equal to or less than 16 A per phase, intended to be connected to public low-voltage distribution systems of between 220 V and 250 V line to neutral at 50 Hz, and not subject to conditional connection.
