Overview
IEC 62386-224:2018 is an international standard published by the International Electrotechnical Commission (IEC) that defines particular requirements for control gear used with non-replaceable light sources (device type 23) within digital addressable lighting interface (DALI) systems. This standard specifically addresses electronic lighting equipment control via digital signals in conformity with IEC 61347 standards, including the addition of direct current (DC) supply compatibility.
As part of the IEC 62386 series, this document complements general requirements for system components and control gear found in Parts 101 and 102 of IEC 62386. IEC 62386-224:2018 is intended to facilitate the interoperability and functional consistency of electronic control devices and lighting control gear in DALI networks, focusing on devices with integrated, non-replaceable light sources.
