which conforms to IEC 61347-1 and IEC 61347-2-2 or for electronic controlgear for LED
modules which conforms to IEC 61347-1 and IEC 61347-2-13.
4.2 General notes on test
The measurement conditions are specified in IEC 61347-1:2010; Annex H: H.1, H.2, H.4, H.8
and H.11; unless otherwise specified in this standard. The device under test (DUT) shall be
placed according to IEC 61347-1:2010; Figure H.1.
An A.C. reference source shall be used to provide input voltage to the DUT. During the tests,
the supply voltage and the frequency shall be maintained constant within ± 0,5 % during the
warm-up period. However, during the actual measurement, the voltage shall be adjusted to
within ± 0,2 % of the specified testing value.
The input voltage source shall be capable of delivering at least three times the input power of
the DUT.
4.3 Controllable controlgear
In case of controllable controlgear the test shall be carried out with the maximum output power.
Requirements of the efficiency during the dimming condition of controllable controlgear are
under consideration.
4.4 Measurement uncertainty
Measurement uncertainty shall be managed in accordance with the accuracy method in 4.4.3 of
the IEC Guide 115:2007.

4.5 Sampling of controlgear for testing
Tests in this part of IEC 62442 are type tests. The requirements and tolerances specified in
this part of IEC 62442 are based on the testing of a type test sample submitted by the
manufacturer for that purpose. This sample should consist of units having characteristics
typical of the manufacturer’s production and be as close to the production centre point values
as possible.
4.6 Number of samples
One specimen shall be tested.

IEC 62442-3:2014 © IEC 2014 – 9 –


4.7 Power supply


Where the test voltage and frequency are not defined by national or regional requirements, the

controlgear manufacturer shall declare the nominal voltage(s) at which the given efficiency is

valid.


Test voltage(s) and test frequency(ies) shall be the nominal voltage and the nominal frequency

of the country for which the measurement is being determined (refer to Table 1).


Table 1 – Typical nominal electricity supply details for some regions

a

Country Nominal voltage and frequency
Europe 230 V; 50 Hz
North America 120 V, 277 V; 60 Hz
b
Japan 100 V, 200 V; 50/60 Hz
China 220 V; 50 Hz
Australia and New Zealand 230 V; 50 Hz

a
Values are for single phase only. Some single phase supply voltages can be double the nominal voltage
above (centre transformer tap). The voltage between two phases of a three-phase system is 1,73 times single
phase values. (e.g. 400 V for Europe).
b
50 Hz is applicable for the Eastern part and 60 Hz for the Western part, respectively.

4.8 Supply voltage waveform
The total harmonic content of the supply voltage when supplying the DUT shall not exceed 3 %;
harmonic content is defined as the root-mean-square (r.m.s.) summation of the individual
components using the fundament as 100 %.
The ratio of peak value to r.m.s. value of the test voltage (i.e. crest factor) shall be between
1,34 and 1,49.
4.9 Substitution load
To give reproducible measurement results, a resistor (R ) shall be used as a replacement
load
for the lamp(s). R is determined from the rated output power and the rated output voltage or
load
rated output current of the controlgear.
The resistor R shall be selected so that the value of the resistance shall not deviate by
load
more than 1 % during the test.

For electronic controlgear for LED lamps/modules a pure resistive load may cause malfunction
of the DUT. In these cases a combination of diodes and variable resistor equivalent to the LED
lamp/module shall be used, which should ensure the maximum rated output current at the rated
output voltage.
NOTE When a special starting procedure is used to allow the constant current controlgear to function properly, the
method with the equivalent resistor can be used.
In case of controlgear with an output frequency higher than 70 Hz for halogen lamps, the load
shall always be a lamp as indicated in 4.2 of IEC 61047:2004.
4.10 Thermocouple and temperature indicator
The resolution of the temperature indicator shall be at least 0,1 °C, when used with the
appropriate thermocouple.

---------------------- Page: 11 ----------------------

4.11 Instrument accuracy


For magnetic transformers, calibrated and traceable a.c. power meters, power analysers or

digital power meters shall be used.


For electronic step-down convertors, all output power measurements shall be made with a

calibrated and traceable wideband power analyser or digital power meter.


For measurements made under the scope of this standard, measurement instruments with the

– current: 1,0 %
– power: 2,0 %
Stability of the measurement values (V, A or W) is given if the data does not differ by more
than 1 % in a time frame of 15 min.
Measurement shall be done in such a way that the line losses are limited (for example with a
four wire measurement system).
Additional tests will be required using an oscilloscope with at least 20 MHz bandwidth or a
spectrum analyser/receiver. This will be required for determination of convertor output
fundamental frequency and harmonics. The power analyser or digital power meter shall have
specified accuracies to within 200 kHz.
4.12 Measuring circuits
In case of controlgear with supplementary connection to the output circuit or sensors (e.g. to
detect fault or temperatures), all sensors and circuits have to be connected as in normal use.
4.13 Multi-rated voltage controlgear

If a controlgear is designed for more than one rated voltages, the controlgear manufacturer
shall declare the rated voltage(s) at which the given efficiency and the standby power are valid.
4.14 Multi-power controlgear
If a controlgear is designed for more than one output power the test shall be carried out with
the maximum output power.
