SOOCIA DDS722 and DTS722 Smart Energy Meters Achieve STS Certification

Recently, the DDS722 Single-Phase Smart Energy Meter and DTS722 Three-Phase Smart Energy Meter , independently developed by SOOCIA , successfully passed STS conformance testing and received Certificates of Conformance issued by the STS Association. The respective certificate numbers are STS26091 and STS26104 .

The certification of both products further strengthens SOOCIA’s international certification portfolio in smart prepaid energy metering, establishing an STS-certified product range covering both single-phase and three-phase applications and providing important technical and certification support for the company’s continued expansion in the global smart metering market.

STS (Standard Transfer Specification) is a widely adopted international standard for prepaid metering. Through standardized technical specifications, STS enables secure and standardized interaction among different components of prepaid metering systems while enhancing interoperability among STS-compliant products. STS conformance certification is also an important technical requirement for prepaid electricity meters in many international utility and power-sector projects.

According to the certifications, the SOOCIA DDS722 Single-Phase Smart Energy Meter and DTS722 Three-Phase Smart Energy Meter were assessed against IEC 62055-41, IEC 62055-51, STS531-4, STS531-5-0, and STS531-6-1-11 Ed 2.3. Both certified products use firmware version V1.0. The certificates confirm that both products have completed the applicable conformance testing and were found to comply with the relevant STS specifications within the scope of the certification testing.

The successful certification of both the DDS722 and DTS722 further expands SOOCIA’s certified smart prepaid metering portfolio across single-phase and three-phase applications. In recent years, the company has continued to develop its smart metering capabilities in response to the requirements of international electricity markets, with ongoing improvements in metering, prepayment, communications, and system integration. Through international certifications and conformance testing, SOOCIA continues to enhance the adaptability of its products to utility projects across different countries and regions.

As smart metering infrastructure continues to expand worldwide, standardization, interoperability, and system compatibility are becoming increasingly important technical requirements for international smart metering projects. SOOCIA will continue to focus on the practical requirements of utilities and power companies worldwide, further advancing product development and its international certification portfolio while providing global customers with reliable and standardized smart metering products and solutions.
