This meter is designed and manufactured with stable performance, low power consumption industrial-grade components and SMT technology. It is suitable for users who implement single-rate electricity prices, such as small and medium-sized enterprises, commercial users and residential users, as well as three-phase electrical equipment. It can be networked via RS485 communication. Product standard: GB/T17215.321.
1,Universal Phase Compatibility:
Single-Phase (1P2W) & Three-Phase (3P4W) Support: Effortlessly monitor residential circuits or industrial three-phase systems with one versatile device.
2,Wide Voltage Range:
Compatible with 80-300V AC (single-phase) and 220/380V AC (three-phase).
3,High-Precision Measurement:
Class 1.0 Accuracy (IEC 62053-21/22): Industry-leading ±1% error margin for billing-grade reliability.
4,Multi-Parameter Tracking: Measures active/reactive/apparent energy (kWh, kVarh, kVAh), voltage, current, power factor, and frequency.
5,RS485 Communication & Protocol Flexibility:
Modbus RTU (Standard): Seamlessly integrate with SCADA, PLCs, BMS, and IoT platforms.
DLT645, M-Bus, or Custom Protocols: Optional protocol support for regional compliance.
6,Baud Rate: Configurable 1200-9600bps for optimal network performance.
7,Robust Design & Safety:
CT/PT Inputs: Directly connect to current transformers (CTs) for high-current applications (e.g., 5A/100A).
Tamper Detection: Alerts for reverse polarity, magnetic interference, and cover removal.
Fire-Retardant Case (PC+ABS): UL94 V-0 rated for enhanced safety.
8,Dynamic Display & Data Logging:
LCD/LED Display: Scrolls real-time parameters (voltage, current, power, kWh).
Event Recording: Stores timestamps for alarms (overload, tampering) and power failures.
9,Certifications & Compliance:
CE, MID (Option), RoHS: Globally certified for quality and metering standards.
