ELECTRICAL INTERFACE SPECIFICATION FOR PHASE-CUT
DIMMER IN PHASE-CUT DIMMED LIGHTING SYSTEMS
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.

The main task of IEC technical committees is to prepare International Standards. However, a

technical committee may propose the publication of a technical report when it has collected

data of a different kind from that which is normally published as an International Standard, for

example "state of the art".

IEC TR 63036, which is a technical report, has been prepared by subcommittee 23B: Plugs,

socket-outlets and switches, of IEC technical committee 23: Electrical accessories.

The text of this technical report is based on the following documents:
Enquiry draft Report on voting
23B/1201/DTR 23B/1214/RVC

Full information on the voting for the approval of this technical report can be found in the

report on voting indicated in the above table.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

The committee has decided that the contents of this publication will remain unchanged until

the stability date indicated on the IEC website under "http://webstore.iec.ch" in the data

related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
A bilingual version of this publication may be issued at a later date.

4 General description

A phase-cut dimmer either cuts the mains voltage immediately after the zero crossing of the

mains (leading edge) or towards the next projected zero crossing of the mains (trailing edge).

The functionality of both methods may be implemented in one device (universal dimmers).

This document describes requirements for phase-cut dimmers during the on state of a lighting

system. Specifications are provided dependent on the dimming method for the conducting

period and the non-conducting period of the phase-cut dimmer and the transitions between

conducting and non-conducting period.

In addition, this document describes requirements for phase-cut dimmers during the off state

of a lighting system. Specifications are provided independently from the dimming method.

5 General requirements
5.1 Voltage rating
This document applies to one or more of the following mains voltages:
100 V, 120 V, 200 V, 230 V, 277 V, according to IEC 60038.
5.2 Frequency rating
This document applies to one or more of the following mains frequencies:
50 Hz or 60 Hz, according to IEC 60038.
5.3 Marking of phase-cut dimmer

The following information should be provided by the manufacturer on the product or in the

accompanying instruction sheets.

Phase-cut dimmers requiring more than one controlgear to function properly should be

marked with the required minimum number of connected controlgear.

Phase-cut dimmers requiring a minimum load should be marked with the required minimum

6 Description of the lighting system and its components
6.1 Wiring method

The wiring of the devices is in accordance with the installation rules given in the IEC 60364

series and also with the national wiring rules applicable in the country where the devices are

installed.
6.2 Wiring diagram

The wiring of the lighting system uses the traditional method of connecting the phase-cut

dimmer to the mains and to the controlgear. Figure 1 is an example of a lighting system with

one phase-cut dimmer and one or two controlgear(s).
---------------------- Page: 11 ----------------------

Regarding the connections of the phase-cut dimmer shown in Figure 1, the drawn lines

represent a two-wire installation and the dashed line represents the direct connection of the

phase-cut dimmer to the mains which is used in three-wire installations.

The direct connection of the phase-cut dimmer to neutral (dashed line in Figure 1) will have

consequences on the power supply requirements and synchronization to the phase-cut

dimmer.

This document defines requirements that enable compatibility between phase-cut dimmers

and controlgear in two-wire installations. However, all predications are also valid for three-

wire phase-cut dimmers to ensure proper operation of controlgear.
