A new edition of IEC 62442-2 has been published by the International Electrotechnical Committee. IEC 62442-2 applies to “Energy performance of lamp controlgear – Part 2: Controlgear for high intensity discharge lamps (excluding fluorescent lamps) – Method of measurement to determine the efficiency of the controlgear.” The new edition is available for purchase on the IEC website.
“IEC 62442-2:2014 defines a measurement method of the power losses of electromagnetic controlgear, the total input power and the standby power of electronic controlgear for high intensity discharged lamps (excluding fluorescent lamps). Also a calculation method of the efficiency for controlgear for high intensity discharged lamp(s) is defined.”
