Switching power supply 3C certification

Switching power supply is a power supply that controls the on and off of the power supply and maintains a stable output voltage. The switching power supply is generally composed of pulse width modulation (PWM) control IC and MOSFET. With the development and innovation of power electronics technology, the switching power supply technology Also constantly innovating.

At present, the switching power supply is widely used in almost all electronic equipment due to its small size, light weight and high efficiency. It is an indispensable power supply method for the rapid development of today's electronic information industry.

Switching power supply products are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instrumentation, medical equipment, semiconductor refrigeration and heating, air purifiers, electronic refrigerators, liquid crystal displays, LEDs Lighting, communication equipment, audio-visual products, security monitoring, LED light bags, computer cases, digital products and instruments and other fields.

What is the 3C certification standard for switching power supply?

The 3C certification standard of switching power supply is mainly based on the national standard GB4943, and the main test items are temperature, safety distance, and abnormal temperature.

Why do switching power supplies require 3C certification?

1. 3C certification is China's compulsory certification. It is a product conformity assessment system implemented by China to protect consumers' personal safety and national security, strengthen product quality management, and implement in accordance with laws and regulations. The so-called 3C certification is China's compulsory product certification system, the English name China Compulsory Certification, the English abbreviation CCC, and the 3C certification mark.

2. 3C is a product conformity assessment system implemented by China in accordance with relevant WTO agreements and internationally accepted rules to protect the lives of consumers, animals and plants, protect the environment, and protect national security.

3. But one thing needs to be emphasized. Not all products of this compulsory certification require 3C certification. 3C certification has a 3C certification catalog. All products within the scope of the catalog must be sold in China. For 3C certification, you don’t need to do it if it is not in the scope of the 3C certification catalog.

4. The switching power supply is within the scope of the 3C certification catalog. Therefore, the switching power supply requires 3C certification before it can be sold in China.

3C certification information required for switching power supply:

1.3C certification application

2. Applicant's registration certificate

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

4. List of key components

5. Product nameplate (electronic file)

6. Product port picture

7. Product appearance picture (mark the nameplate position)

8. Chinese product manual (electronic file)

9. Whether to sell with wire components (the default is to sell with wire components, if not, you need to provide a statement, EBO can provide template reference)

10. Product difference statement (required for each model)

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