1 Scope
This document specifies the performance requirements for the electronic control gear using a DC power supply below 1 000 V and an AC power supply of 50 Hz or 60 Hz, whose output frequency is different from the power supply frequency. This control gear works with the LED modules specified in GB 24819. The LED control gear specified in this document is designed to provide a constant voltage or current. This document also covers types that do not comply with pure voltage and current.
This document applies to the electronic control gear for LED modules with a DC power supply below 1 000 V and an AC power supply of 50 Hz or 60 Hz.
Note 1: The tests in this document are type tests. Test requirements for individual control gears during production are not included.
Note 2: The requirement for a control gear equipped with a device capable of changing the output power is still under study.
Note 3: It can be expected that, as long as the LED module manufacturer?€?s product specifications are considered, the control gear in accordance with this document can guarantee normal operation between 92% and 106% of the rated supply voltage.

4.1 The tests specified in this document are all type tests. The requirements and tolerances stated in this document are based on tests performed on type test samples submitted by the manufacturer for this purpose. Such type test samples shall generally have the typical characteristics of the manufacturer?€?s product and shall be as close as possible to the center point value of the product.
According to the output voltage, it is divided into:
a) control gear with a stable output voltage;
b) control gear without a stable output voltage.
5.3 Classification according to output current
According to the output current, it is divided into:
a) control gear with a stable output current;
b) control gear without a stable output current.
5.4 Classification according to output isolation
According to the output isolation, it is divided into:
a) isolated output control gear;
b) self-coupling control gear (i.e., non-isolated output control gear). 6 Marking
6.1 Mandatory marking
6.1.1 The control gear shall be clearly marked with the following:
Circuit power factor, for example: ?? = 0.9.
For control gear where the power factor is not constant over the rated output range and/or has a supply voltage range, the power factor may vary for different combinations of supply voltage and output power. In this case, the range of power factor, for example ?? = 0.8 ~ 0.9, shall be indicated on the control gear.
If the power factor is less than 0.95 leading, the letter C shall be added after it, for example ?? = 0.9C.
6.1.2 In addition to the above mandatory markings, the following information shall also be marked on the control device or indicated in the manufacturer?€?s catalog or similar documents:
a) the allowable temperature range, if applicable;
b) an indication that the control gear has a stable output voltage, if applicable; c) an indication that the control gear has a stable output current, if applicable; d) an indication that the control gear is suitable for use with the mains dimmer, if applicable;
e) a statement of the mode of operation, e.g., phase control, if applicable; f) Prated_min, the rated minimum output power of the control gear for normal operation, if applicable.
Note: Prated_min can be a marking with Prated, e.g., Prated = 20 W, ..., 60 W. 6.2 Optional marking
