Description of the full extra low voltage control unit.
The following is an analysis of the product labeling problems encountered in the inspection, according to the installation method of the LED control device and the protection against electric shock: Figure 1:
Figure 1 Product Marking Problem: Sample Name: Constant Current LED Controller, CQC12-461224-2011 LED DC or AC Electronic Controller Safety and Electromagnetic Compatibility Certification Rules 4.1.2 Sample Marking Requirements: in the sample product label The product name should use the standard name "DC/AC Electronic Controller for LEDs" or simply the LED control unit. LED adapters, LED switching power supplies, LED drivers, LED converters, etc., which may be confused with other certified products, and other additional names such as high precision, high intelligence, and full range are not accepted.
Figure 2 Product logo issues:
1 Sample name: LED power adapter, does not accept such a name.
2 This LED control unit is built-in, not stand-alone, so IP20 and can not be placed on the mark; and SELV should be changed to SELV-equivalent (equivalent SELV).
Figure 3 Product logo issues:
1 No sample name, LED control should be added.
2 Uncertainty is constant voltage type or constant current type. If it is constant pressure type, it should be marked OUTPUT: +36V
Max3.4A; if it is a constant current type, it should be marked Max 36V 3.4A.
Figure 4 Product logo issues:
The symbol is the symbol in Appendix I (stand-alone SELV product) of the GB19510.14-2009 standard . Since the control device in the figure is not SELV, this symbol cannot be marked.
Figure 5 Product logo:
This LED control unit is a qualified mark that includes stand-alone, Class II, SELV, short-circuit proof, and luminaire standards. The sign can be directly installed on the surface of ordinary combustible materials .
Note: All of the above products are labeled to ensure corporate privacy, and the trademark and manufacturer names have been removed.
In summary, the summary is as follows:
1. When making product certification, the enterprise should firstly belong to which type of control device according to the structural characteristics of its own control device. Figure 3 and Figure 4 are independent, Figure 1 and Figure 2 are built-in, and no case is attached. Integral.
2. According to the classification of anti-shock protection, confirm which line the line of the control device meets, such as
Equivalent safety extra low voltage standard SELV-equivalent; isolated control device should be marked ; Safety extra low voltage control device should be marked SELV;
3. Then confirm whether the control device belongs to constant voltage type or constant current type. The constant voltage type should be rated output voltage value and output current range value; the constant current type should be rated output current value and maximum output voltage value.
