On April 28, 2022, the power supply products independently developed and produced by Jiangsu Liankang Information Co., Ltd. (referred to as Liankang Information) successfully passed the evaluation of the China Quality Certification Center and obtained the China Compulsory Product 3C Certification Certificate, which is valid until April 27, 2027.

3C certification is a mandatory and authoritative certification for domestic electronic product market access. Products must pass rigorous safety, electromagnetic compatibility, and other comprehensive tests, comply with national mandatory standards such as GB 17625.1 and GB 4943.1, and be approved for production, sales, and market circulation. It is the core certificate of product safety, quality, and compliance capabilities.

To meet the requirements of the company's audio and RF testing modules and automated testing equipment, Liankang Information independently developed a matching power supply, strictly following national electrical safety standards throughout the design, trial production, and testing process. This certification covers the entire range of supporting power products. After multiple indicator tests by authoritative institutions, the products have met the standards in terms of electrical safety, electromagnetic interference, and stable battery life, and have successfully passed the full audit process.

The implementation of this 3C certification marks that the company's power supply supporting products have complete market compliance qualifications and can be matched with its own testing equipment for synchronous external supply, further improving the company's upstream and downstream supporting industry chain and enhancing the integrated supply capability of complete machine products. Subsequently, Liankang Information will continue to strictly adhere to product safety standards, improve the inspection and control system for all categories of components, and provide compliant and reliable product quality services to electronic manufacturing customers.
