The safety of DC stabilized power supplies is crucial to ensure user safety and product reliability. To this end, DC stabilized power supplies must comply with specific safety standards and pass relevant certifications. This helps reduce the risk of electrical accidents and ensures that products can be sold in the global market. This article will explore the common safety standards and certification processes for DC stabilized power supplies.

I. Main Safety Standards

1.International Electrotechnical Commission (IEC) Standards

– IEC 60950-1: Covers safety requirements for information technology equipment.

– IEC 62368-1: A more modern safety standard for information technology and communication equipment, gradually replacing IEC 60950-1.

2.European Standards (EN)

– EN 55032: Related to electromagnetic compatibility, focusing on emissions.

– EN 55035: Related to electromagnetic compatibility, focusing on immunity.

3.American National Standards (UL)

– UL 60950-1: Corresponds to IEC 60950-1, used to evaluate the safety of information technology equipment.

– UL 62368-1: Provides safety guidelines for a wider range of technological equipment.

II. Certification Process

1.Design Phase

– Consider all relevant safety standards early in the product design phase.

– Integrate necessary safety features such as overcurrent protection, overtemperature protection, and structural protection.

2.Sample Testing

– Rigorous testing of product samples is required before obtaining formal certification.

– Testing includes electrical safety, mechanical safety, fire risk, and electromagnetic compatibility.

3.Certification Agency Review

– Independent assessment by a third-party certification agency (such as TÜV, SGS, or UL).

– Submit detailed product documentation and test reports for review.

4.Obtaining Certification

– After successfully passing all tests and reviews, the product will be awarded the corresponding safety mark.

– This mark is proof that the product meets specific safety requirements.

III. Maintaining and Updating Certification

1.Periodic Reviews

– Product certification usually requires periodic reviews to ensure continued compliance with safety standards.

– Any significant design changes require re-evaluation and certification.

2.Tracking New Safety Regulations

– Safety standards may be updated, so it is necessary to continuously follow industry trends and regulatory changes.

– Update product designs in a timely manner to meet new safety requirements.

IV. Summary

The safety standards and certifications for DC stabilized power supplies are key factors in ensuring the safe operation of products in the global market. By following international and regional safety standards, manufacturers can not only improve the market competitiveness of their products but also significantly reduce legal and safety risks that may arise due to product failures. Therefore, it is an important responsibility for every power equipment manufacturer to deeply understand and implement these safety measures.
