Eastron Secures China's First UL Certification for AC Smart Meters, Leading the Global Market

Zhejiang Eastron Electronic Co. Ltd. (hereinafter referred to as “Eastron”) announced that its AC smart meter series products (SDM230 series, SDM630 series, and SDM630MCT series) have successfully passed rigorous certification by UL (Underwriters Laboratories), a global leader in safety science, and obtained UL certification. This milestone not only makes Eastron the first domestic manufacturer of AC smart meters to achieve UL certification but also underscores its international leadership in product safety, reliability, and technological innovation.

UL Certification: The “Gold Standard” of Global Safety

Established in 1894, UL certification is a globally recognized authority in safety standards, covering critical areas such as electrical safety, fire resistance, and mechanical design. It is hailed as a “global passport” for product safety. To earn UL certification, products must undergo hundreds of laboratory tests and manufacturing process audits, ensuring compliance with stringent requirements in North America and international markets. For power meters, UL certification signifies reduced risks of electrical fires and leakage, while significantly enhancing user trust and brand competitiveness.

As the first Chinese manufacturer to achieve this honor, Eastron demonstrated its R&D capabilities and lean manufacturing system by passing UL's comprehensive audits on product design, material selection, and production processes. This achievement validates Eastron's technical expertise and quality control standards in the global smart meter industry.

Dual Source Smart Meter Series: Innovative Technology Sets Industry Benchmarks

The UL-certified product line includes Eastron's dual source smart meters, designed for complex energy scenarios to meet demands for multi-source metering, high-precision monitoring, and intelligent management:

UL Certification Drives Market Expansion: Unlocking Global Premium Markets

With UL certification, Eastron's smart meter series now gains the following competitive advantages:

Safety Credibility: The UL mark serves as a “mandatory entry permit” for North American markets while boosting customer trust in regions like Europe and Southeast Asia that recognize UL standards.

Technological Breakthroughs: The certification process spurred design optimizations (e.g., fire-resistant materials, enhanced insulation), laying the foundation for future high-value-added product development.

Market Potential: The global smart meter market is projected to exceed $12 billion by 2025. UL certification positions Eastron to penetrate premium sectors such as North America's renewable energy infrastructure and micro-grid projects.

Future Vision: Advancing Sustainability Through Global Standards

Eastron will continue collaborating with UL and other international institutions to promote smart meter applications in smart cities and zero-carbon industrial parks. This certification marks a pivotal step in the company's global strategy and serves as a powerful testament to China's capability to deliver high-standard, cutting-edge products to the world.
