Manufacturing Capabilities and Engineering Expertise

Incoming Quality Control (IQC)

100% inspection of critical components including microcontrollers, high-stability current transformers (CT), and V0-grade flame-retardant enclosures to prevent fire hazards.

100% High-Precision Calibration

Utilizing multi-position automatic calibration benches to verify accuracy class under multiple power factors (PF=0.5L, 1.0, 0.8C) and varying temperature loops.

Environmental Stress & Burn-In

All meters undergo accelerated aging and heat soak testing (55°C to 70°C) under full load simulation to weed out early component infant mortality.

Robust EMC & Surge Immunity

Verified in our in-house lab to withstand severe lightning surges (up to 4kV/6kV standard, expandable to 12kV), electrostatic discharges (ESD), and electromagnetic fields.

Batch Traceability

Every meter is embedded with a unique serial number, linking it to its specific components, production line date, and calibration data logs for lifetime tracking.

International Standards and Certifications

Our three-phase electricity meters are designed to meet global regulatory requirements:

• IEC 62052-11 (General requirements)
• IEC 62053 series (Accuracy standards)
• MID certification (Compliance with European billing requirements)
• CE certification (Compliance with EU safety requirements)
• ISO 9001 Quality Management System

Frequently Asked Questions

Q: Do your smart meters support interoperability with third-party Head-End Systems (HES)?

A: Yes. Our three-phase smart meters are designed in strict compliance with DLMS/COSEM (IEC 62056) standards. They have been verified to seamlessly interface with major global AMI/AMR platforms, ensuring plug-and-play interoperability without proprietary vendor lock-in.

Q: How do your meters handle power quality events and anti-tampering?

A: Our meters feature dedicated non-volatile memory to record severe power quality events (such as voltage sags, swells, phase loss, and current unbalance). For anti-tampering, they detect and log terminal cover openings (even when unpowered), bypass attempts, reverse wiring, and strong magnetic field interferences, instantly triggering alerts via the communication module.

Q: What is your typical lead time for custom OEM/ODM orders?

A: For standard configurations or evaluation samples, our lead time is 7–10 days. For bulk OEM orders involving customized plastic molds, unique terminal block configurations, or customized firmware/protocols, mass production typically spans 4 to 6 weeks, depending on the component sourcing schedule.

Q: Can your meters handle dual-source or backup generator billing?

A: Yes. We offer customized firmware configurations that support multi-channel profiling. The meters can separate utility grid consumption from auxiliary/backup generator tracking via external digital inputs, enabling clear tariff allocation for microgrids.
