UNE-EN IEC 62442-2:2022

This part of IEC 62442 defines a measurement method of the power losses of electromagnetic

controlgear, the total input power and the standby power of electronic controlgear for discharge

lamps (excluding low-pressure mercury fluorescent lamps). A calculation method of the

efficiency of controlgear for discharge lamp(s) is also defined.

It is assumed that the controlgear 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.

This document applies to electrical controlgear-lamp circuits comprised solely of the controlgear

and of the lamp(s).

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 lamp controlgear efficiency for all controlgear sold for

domestic and normal commercial purposes operating with discharge lamps.

This document does not apply to:

controlgear which form an integral part of lamps;

controlgear circuits with capacitors connected in series;

controllable electromagnetic controlgear.
