EN IEC 61000-3-2:2019/A1:2021 pdf free.Electromagnetic compatibility (EMC) – Part 3-2: Limits – Limits for harmonic current emissions (equipment input current≤16 A per phase) (IEC 61000-3-2:2018/A1:2020).
5.1 General
Replace the first sentence under Class 0 with the following.
Equipment having a specified power less than or equal to 600 W according to 6.3.2. of the following types:
5.2 DescrIption of lighting equipment
Replace the existing text with the following:
In this document, lighting equipment as defined in 3.13 includes:
— light sources, lamps, integrated lamps and luminaires;
— the lighting part of multi-function equipment where one of the primary functions of this is illumination;
— independent lighting control gear;
— ultraviolet (UV) and infrared (IR) radiation equipment;
— illuminated advertising signs;
— independent dimmers, other than phase control types, for lighting equipment; DLT control devices.
In this document, lighting equipment as defined in 3.13 excludes:
— lighting devices built in equipment with another primary purpose, such as photocopiers, overhead projectors and slide projectors, or employed for scale illumination or indication purposes;
— household appliances whose primary function is not for generating and/or regulating and/or distributing optical radiation, but which contain one or more light sources with or without a separate switch (e.g. a range hood with a built-in light source);
— independent phase control dimmers;
— professional luminaires for stage lighting and studios;
— emergency luminaires that emit light only during emergency mode;
— professional appliances whose primary function is to present lighting devices for exhibition purposes;
— mechanical switches and relays, and other simple devices providing on/off control only, that do not produce distorted currents.
Add, after 5.2, the following new subclause:
5.3 External power supplies
EPS shall be classified according to the types of equipment they are designated for, as specified in the instructions for use.
NOTE See also Clause B.17.
6.2 Control methods
Replace the existing text with the following:
Asymmetrical controls according to IEC 60050-161:1990, 161-07-12, and half-wave rectification directly on the mains supply may only be used where:
a) they are the only practical solution permitting the detection of unsafe conditions, or
b) they control an active input power less than or equal to 100 W, or
C) they are operated in a portable equipment fitted with a two-core flexible cord which is intended for use for a short period of time, i.e. for a few minutes only.
If at least one of these three conditions is fulfilled, half-wave rectification may be used for any purpose, whereas asymmetrical controls may only be used for the control of motors.
NOTE I Equipment which can fulfil condition C) includes, but Is not limited to, hair dryers, electrical kitchen appliances and portable tools
NOTE 2 When using asymmetrical controls or half-wave rectification under the above circumstances, the input current has a DC component that can disturb certain types of protection devices In case of an earth fault. See
IEC TR 60755,
Even though asymmetrical controls and half-wave rectification are permitted under the conditions given above, equipment shall still comply with the harmonic requirements of this document.
In general, symmetrical controls may be used for any application and without particular restrictions. However, symmetrical control methods which can produce integer harmonics of the mains frequency up to the 40th order in the mains input current may be used to control the power supplied to heating elements only if at least one of the following restrictions is met:
• the full sine-wave active input power of these heating elements is lower than or equal to 200 W, or
• the limits of Table 3 are not exceeded when testing with these heating elements active.
Such symmetrical control methods are also allowed for professional equipment provided that either one of the above conditions is fulfilled, or the relevant emission limits according to Clause 7 are not exceeded when tested at the supply input terminals and in addition both the following conditions are fulfilled:
— it is necessary to control precisely the temperature of a heater whose thermal time constant is less than 2 s, and
— there is no other technique economically available.
Professional equipment whose primary purpose, considered as a whole, is not for heating, shall be tested against the relevant emission limits according to Clause 7.EN IEC 61000-3-2 pdf download.
