IEC 62442-3 (REDLINE + STANDARD)

Abstract

This part of IEC 62442 defines a measurement method for the power losses of electromagnetic transformers as well as the power losses and the standby power of electronic convertors for tungsten-halogen lamps and for LED light source(s). It is applicable for controlgear that are designed for use on DC supplies up to 1 000 V and/or AC supplies up to 1 000 V at 50 Hz or 60 Hz. A calculation method of the efficiency of the mentioned controlgear for tungstenhalogen lamps and LED light source(s) is also defined. This document 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. NOTE Requirements for testing individual controlgear during production are not included. This document specifies the measurement method for the total input power, the standby power and the calculation method of the controlgear efficiency for all controlgear sold for domestic and normal commercial purposes operating with tungsten-halogen lamps and LED light source(s). The term "LED light sources" includes LED modules and LED lamps. This document does not apply to: – controlgear which form an integral part of lamps (LED light sources); – controlgear circuits with capacitors connected in series; – controllable electromagnetic controlgear.
