IEC 62384-2020发光二极管(LED)模块用直流或交流电源电子控制装置. 性能要求

This document specifies performance requirements for electronic controlgear for use on DC or AC supplies up to 1000 V (alternating current at 50 Hz or 60 Hz) and with an output frequency which can deviate from the supply frequency, associated with LED modules according to IEC 62031. Controlgear for LED modules specified in this document are designed to provide constant voltage or current. Deviations from the pure voltage and current types do not exclude the gear from this document. NOTE 1 The tests in this document are type tests. Requirements for testing individual controlgear during production are not included. NOTE 2 Requirements for controlgear which incorporate means for varying the output power are under consideration. NOTE 3 It can be expected that controlgear complying with this document will ensure satisfactory operation between 92 % and 106 % of the rated supply voltage, taking into account the specifications of the LED module manufacturer.
