prBAS EN IEC 61820-3-2:2026

IEC 61820-3-2:2023 specifies the requirements for power electronic converter systems (PECS) dedicated to powering aeronautical ground lighting (AGL) circuits with series circuit topology. An example of a traditional implementation is an AGL circuit with 6,6 A RMS nominal current, powered by a constant current regulator (CCR). In addition to revising the requirements for 6,6 A CCR setups, this document introduces requirements for general PECS for new AGL systems including systems specifically designed for LED based luminaires. This first edition cancels and replaces IEC 61822 published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 61822:2009: a) introduction of power electronic converter systems (PECS) to be used in the aeronautical ground lighting systems other than the 6,6 A aeronautical ground lighting systems; b) introduction of classification for different device types; c) introduction of IEC 62477-1:2022 and IEC 62477-2:2018 as the basis for safety related requirements.
