        1. 3C certification application

        2. The applicant's business license and organization code certificate

        3. Product structure diagram, circuit schematic diagram, exploded diagram, etc.

        4. List of key components

        5. Product nameplate (electronic file)

        6. Dimensional drawing of internal insulation sheet

        7. Transformer and inductor specifications

        8. Chinese product manual (electronic file)

        9. Whether to sell components with wires, use altitude and use climatic conditions.

        10. Product difference statement (required for each model)

        11. Model comparison table of both parties (to be provided for ODM model application)

        3C certification process for switching power supply

        1. Application acceptance;

        2. Document review;

        3. Receipt of sent samples;

        4. Sample test and check data;
