This international standard specifies performance requirements for electronic controlgear for use on DC or AC supplies up to 1000 V (AC 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 standard are designed to provide constant voltage or current. Deviations from the pure voltage and current types do not exclude the gear from this standard. NOTE 1 The tests in this standard 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 may be expected that controlgear complying with this standard will ensure satisfactory operation between 92 % and 106 % of the rated supply voltage, taking into account the specifications of the LED module manufacturer.
