Overview
EN IEC 63128:2019 is an international standard developed by the International Electrotechnical Commission (IEC) and adopted by the Comité Européen de Normalisation Électrotechnique (CENELEC). This standard specifies the analogue voltage dimming interface for electronic current sourcing controlgear used in lighting applications. It defines the control interface allowing the output power of electronic controlgear to be dimmed between minimum/off and maximum levels through a voltage control device that sinks the controlgear's current source.
This standard addresses the functionality and performance of the analog dimming control interface, focusing on system interoperability and consistent dimming behavior. It does not cover safety requirements for the analogue interface, which are specified separately in the IEC 61347 series.
Key Topics
Scope & Purpose: Specifies an analogue control interface for dimming purposes of electronic lamp controlgear. The controlsignal is a DC voltage within the range of -20 V to +20 V, used to regulate the output power of the controlgear.
Controlgear Definition: Includes electronic devices that regulate electrical power supplied to light sources, such as lamps or LED modules, providing functions such as dimming, power factor correction, and radio interference suppression.
Control Signal Characteristics: Details requirements for voltage ranges and protection against reversed polarity to ensure robust and safe operation.
System Architecture: Supports connection of multiple controllable lamp controlgears to a single control device, enabling scalable dimming solutions for various lighting installations.
Testing Requirements: Specifies type testing procedures to validate compliance of controlgear with the analog voltage dimming interface, including tests for disconnected control signals and operational performance.
Marking Requirements: Mandates clear marking of controlgear to indicate compliance with the standard, facilitating identification and interoperability.
Applications
EN IEC 63128:2019 is crucial for manufacturers, system integrators, and designers involved in:
Lighting Installation Systems: Ensuring consistent dimming performance across electronic controlgear in residential, commercial, and industrial lighting systems.
Electronic Lamp Controlgear Production: Designing and certifying electronic ballasts and LED drivers with analogue voltage dimming control inputs that meet interoperability criteria.
Building Automation and Smart Lighting: Integrating analogue dimming control interfaces within building management systems for energy-efficient lighting control.
Retrofit and New Installations: Enabling straightforward integration of dimmable controlgear with existing analogue voltage control devices for enhanced lighting ambience and efficiency.
Multiple Controlgear Management: Simplifying wiring and control of multiple luminaires by allowing several controlgear units to share a single analogue control voltage source.
Related Standards
To fully address safety and other operational aspects, EN IEC 63128:2019 references relevant IEC standards, including:
IEC 61347 Series: Covers safety requirements for lamp controlgear including electronic ballasts and LED controlgear.
IEC 62386 Series: Defines digital communication protocols for lighting control but is excluded from the analogue control signal scope.
IEC 60081, IEC 60901, IEC 60929: Standards governing specific lamp types and their associated controlgear.
ISO 2859-1: Sampling procedures and inspection by attributes used for type testing according to this standard.
Practical Value
Compliance with EN IEC 63128:2019 ensures:
Reliable and standardized analogue voltage dimming interfaces for electronic current sourcing controlgear.
Enhanced compatibility between manufacturers’ devices, leading to easier system integration.
Improved lighting quality and energy management through precise dimming control.
Reduction in installation complexity when deploying multiple dimmable light sources.
Confidence for end users and specifiers that lighting control systems meet international quality standards.
By adhering to EN IEC 63128:2019, the lighting industry advances towards more interoperable, safe, and efficient analogue dimming solutions, enabling optimized lighting environments in various applications worldwide.

LIGHTING CONTROL INTERFACE FOR DIMMING –

ELECTRONIC CURRENT SOURCING CONTROLGEAR
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
