1 Scope
This standard specifies performance requirements for electronic control gear for use on d.c. supplies up to 250 V and a.c. supplies up to 1 000 V at 50 Hz or 60 Hz with an output frequency which can deviate from the supply frequency, associated with LED modules according to GB 24819.Control gear for LED modules specified in this standard are designed to provide constant voltage or current. Deviations from the pure voltage and current types do not exclude the gear from this standard.
Note 1: the tests in this standard are type tests. Requirements for testing individual control gear during production are not included.
Note 2: requirements for control gear which incorporate means for varying the output power are under consideration.
Note 3: it may be expected that control gear complying with this standard will ensure satisfactory operation between 92 % and 106 % of the rated supply voltage, taking into account the specifications of the LED module manufacturer.
