Switching power supply 3C certification

Switching power supply 3C certification standard

The 3C certification standard of switching power supply is mainly based on the national standards GB4943, GB8898 and GB4706.

Switching power supply is required to provide information for 3C certification

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;

5. The laboratory produces a draft;

6. The draft is correct, upload it 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 certification.

(For factory level C or D, the certificate can only be obtained after factory inspection)
