This document specifies safety requirements for electronic controlgear for LED light sources for use on DC supplies up to 1 500 V or on AC supplies up to 1 000 V at 50 Hz or 60 Hz. This document is applicable for controlgear with an output voltage (RMS) not higher than 1 000 V. NOTE 1 Control units, such as devices connected between power supply unit and LED light sources that control or adjust the operation of LED light sources, are covered by this document. NOTE 2 Performance requirements are covered by IEC 62384. NOTE 3 Such controlgear can also be used for electric sources producing optical radiation with the same technology used for purposes different than illumination and producing radiation other than visible spectrum.
