IEC 62384:2011 pdf – DC or AC supplied electronic control gear for LED modules – Performance requirements.
For control gear having a non-stabilised output current, when supplied with the rated supply voltage, the output current shall not differ by more than ±10 % from the rated current of the LED modules; for control gear having a stabilised output current when supplied at any supply voltage between 92 % and 106 $ of the rated supply voltage, the output current shall not differ by more than ±10 % from the rated current of the LED modules.
Multiple load control gear shall be tested with both the minimum and maximum load.
7.3 Capacitive load requirement
If the LED module or any additional control unit connected to the convertor contain capacitors for control and/or driving circuitry on the modules, current pulses may be generated when connecting the LED module to the control gear This shall not disturb the control gear overcurrent detection nor the starting process of the control gear.
For test conditions, See clause A,2. Figure Ala describes a test circuit during the starting process of the control gear and figure describes a test circuit for connecting the load during steady state operation.
Compliance: when connecting the measurement circuit to the control gear, the detection device shall not trip.
7.4 Voltage surges during switching and operation
Voltage surges superimposed on the output voltage shall not exceed the values specified
below (values under consideration).
8 Total circuit power
At rated voltage, the total circuit power shall not be more than 110 % of the value declared by
the manufacturer, when the control gear is operated with LED modulef s). 9 Circuit power factor
The measured circuit power factor shall not be less than the marked value by more than 0,05 when the control gear is operated on its rated wattage with LED module(s) and the whole combination is supplied with rated voltage and frequency.
10 Supply current
At rated voltage, the supply current shall not differ by more than +10 % from the value marked on the control gear or declared in the manufacturer’s literature, when that control gear is operated on its rated wattage with LED module(s).
11 Impedance at audio-frequencies
Control gear marked with the audio’frequency symbol I (see subclause 6.2b)) shall be tested In accordance with Clause A.3, using the circuit in Figure A.2.
For every signal frequency between 400 Hz and 2 000 Hz. the impedance of the control gear when operated with the rated LED module load at rated voltage and frequency shall be inductive in characteristic. Its impedance in ohms shall be at least equal to the resistance of the resistor which would dissipate the same power as the LED module-control gear combination when operating at its rated voltage and frequency. The control gear impedance is measured with a segnai voltage equal to 3,5 % of the rated supply voltage of the control gear
12 Operational tests tor abnormal conditions
The control gear shall not be damaged under following conditions.
a) Test without LED module(s) inserted
The control gear shall be supplied with rated voltage for I h without LED module(s) inserted. At the end of this test, the LED module(s) shall be connected and shall operate normally.
b) Tesl for reduced LED module resistance Under consideration.
c) Tests for short-circuit proot control gear
The control gear is short-circuited for 1 h or until a protecting device opens the circuit.
After these tests and after restoration of a possible protecting device, the control gear shall function normally.
13 Endurance
13.1 The control gear shall be subjected to a temperature cycling shock test and a supply voltage switching test as follows
a) Temperature cycling shock lest
The non-energised control gear shall be stored firstly at —10°C or if the control gear is marked with a lower value, at that value for I h. The control gear is then moved into a cabinet having a temperature of tc and stored for 1 h. Five such temperature cycles shall be carried out.
b) Supply voltage switching test
At rated supply voltage the control gear shall be switched on and off for 30 s. The cycling shall be repeated 200 times with no load and 800 times with maximum load conditions.
LED modules failing during this test shall be replaced immediately.
At the end of these tests the control gear shall operate an appropriate LED module or LED modules correctly for 15 mm.
13.2 The control gear shall then be operated with an appropriate LED module/with appropriate LED modules at rated supply voltage and at the ambient temperature which produces t. until a test period ot 200 Ii has passed. At the end 01 this lime, and after cooling down to room temperature, the control gear shall operate an appropriate LED module/appropriate LED modules correctly for 15 mm. During this test the LED module(s) is (are) placed outside the test enclosure in an ambient temperature of (25 ± 5)°C.
