Overview

EN IEC 62386-250:2023 - Digital addressable lighting interface, Part 250 - specifies the particular requirements for an integrated power supply (device type 49) that provides bus power inside a lighting control gear. Published by CLC and aligned with IEC 62386-250:2023, this part builds on the wider IEC 62386 series and is applicable only to control gear that complies with IEC 62386-102. It defines how an integrated bus power supply behaves, communicates and is configured within a digital addressable lighting system.

Key topics and technical requirements

This standard addresses the functional and protocol-level characteristics of a bus power supply integrated in control gear. Key technical topics include:

• Electrical specification - electrical characteristics for the integrated bus power supply (see Clause 5).
• Bus power supply ratings and status - current rating and status reporting of the bus power source (Clause 6).
• Transmission protocol structure and timing - message framing and timing requirements for reliable communications on the lighting bus (Clauses 7–8).
• Method of operation and configuration - capabilities, configuration and memory organization for the device (Clause 9). This includes memory bank management and rules for writing memory banks.
• Memory banks and identification - mandatory memory bank definitions (e.g., Memory Bank 201 for device identification).
• Variables and commands - declaration of variables and standardized commands for querying and controlling the integrated power supply (Clauses 10–11). Examples in the standard include QUERY ACTIVE POWER SUPPLY and ENABLE DEVICE TYPE commands.
• Conformance and normative references - designed to be used in conjunction with EN IEC 62386-101:2022, EN IEC 62386-102:2022 and related parts (Annex ZA).

Applications and who uses it

This standard is primarily intended for:

• Manufacturers of lighting control gear with an integrated bus power supply (device type 49).
• System designers and specifiers who integrate control gear into building lighting systems.
• Test laboratories and conformity assessment bodies that verify compliance with IEC 62386 series requirements.
• Controls engineers and product managers defining firmware and communication behavior for integrated power-supplied devices.

Practical applications include ensuring interoperable bus powering and predictable control behavior in digitally addressable lighting installations, and enabling reliable status reporting and remote queries of the integrated power source.

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
