DIN EN IEC 62442-3 VDE 0712-27:2019-03

This part of the IEC 62442 series defines a measurement method for the power losses of electromagnetic transformers as well as and the power losses and with the standby power of electronic convertor for tungsten halogen lamps and for LED light source(s)lamps and LED modules.
It is assumed that the controlgear are designed for the use on a.c. supplies up to 1 000 V at 50 Hz or 60 Hz.
Also a calculation method of the efficiency for the mentioned controlgear for tungsten halogen lamps and lamps and LED light source(s)modules iI is defined.
This part of IEC 62442 applies to electrical controlgear - lamp circuits comprised solely of the controlgear and of the lamp(s) (LED light sources).
For multipurpose power supplies only the lighting part will be considered.
