Switching power supply 3C Certification standards

The 3C certification standard of switching power supply is mainly based on the national standards gb4943, gb8898 and GB4706.

Switching power supply handling 3C Certification is required to provide information

1. Application for 3C certification

2. Applicant's business license and organization code certificate

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

4. List of key components

5. Product name plate (electronic file)

6. Dimension drawing of internal insulating sheet

7. Transformer and inductance specification

8. Chinese product manual (electronic file)

9. Whether to sell with wire components, use altitude, use climate conditions.

10. Product difference statement (to be provided for each model)

11. Model comparison table of both parties (ODM mode application shall be provided)

Switching power supply handling 3C Certification process

1. Accept the application;

2. Data review;

3. Sample receiving for sample delivery;

4. Sample test, check data;

5. Laboratory draft;

6. The draft is correct and uploaded for review;

7. CQC preliminary evaluation - + re evaluation - + certificate issuance;

8. Printing, receiving, sending and management of certificates;

9. Factory inspection within 3 months after the first application for 3C certificate.

(for factory level C or D, the evidence can only be obtained after factory inspection)
