Manufacturing Excellence & Quality Assurance Infrastructure

Precision SMT Assembly
Our cleanroom production uses high-speed Yamaha and Panasonic SMT lines, combined with 3D AOI and X-ray inspection, ensuring highly reliable and defect-free solder joints on every metering PCB.

100% Automated Calibration
Each single-phase meter undergoes fully automated calibration on multi-position test benches. The system verifies accuracy across multiple load points under Class 1.0 / Class 2.0 standards, eliminating manual intervention and ensuring consistency.

Environmental Stress Testing
Every batch is validated through rigorous in-house reliability tests, including:

• Thermal aging: 48-hour burn-in at up to +70°C
• Dielectric & impulse tests: surge resistance up to 6kV/10kV
• EMC testing: ESD and RF immunity for stable signal performance
• Full Traceability System

Technical FAQ

Q: Can your smart single phase meters integrate with our existing third-party Head-End System (HES)?

A: Yes. Our smart meters strictly adhere to the DLMS/COSEM (IEC 62056) protocol and are officially certified by the DLMS User Association. This guarantees seamless, vendor-independent interoperability with any standard compliant HES or MDM software layer.

Q: Do you provide firmware customization for local grid code compliance?

A: Absolutely. Our in-house R&D team regularly configures firmware parameters to support specific regional multi-tariff structures (TOU), custom load profile logging intervals, specific anti-tamper event thresholds, and local encryption keys.

Q: What is your typical lead time for a large-scale utility deployment (e.g., 50,000 units)?

A: For standard configurations, our automated manufacturing lines can fulfill a 50,000-unit order within 4-6 weeks after technical specification sign-off and component sourcing confirmation. We provide milestone tracking and comprehensive FAT (Factory Acceptance Testing) validation video logs.

Q: How do your meters perform during major grid voltage fluctuations or lightning surges?

A: Our single phase meters feature robust power supply modules with built-in metal oxide varistors (MOVs) designed to withstand prolonged over-voltages (up to 440V AC continuous) and successfully pass 6kV/10kV impulse voltage surge tests according to IEC standards.
