Core Advantages
- The 2P (36mm) compact width minimizes panel space requirements, allowing for higher density installations in standard distribution boards.
- Built-in RS485 communication utilizing the standard Modbus-RTU protocol provides seamless integration into existing BMS and EMS networks.
- Utilizes a high-precision manganin shunt sampling mechanism to mitigate risks associated with external DC magnetic interference.
- The UL94-V0 rated polycarbonate enclosure offers high-duty flame retardancy, self-extinguishing within 10 seconds to enhance electrical safety.
- Heavy-duty reinforced connection terminals are engineered to handle continuous high-current loads with minimal thermal accumulation.

System Architecture & Integration
The meter functions as a highly responsive edge data node, integrating into standard automation networks and energy management platforms via its isolated RS485 serial port.
Data Topology Meter → Modbus-RTU / RS485 → Data Gateway → MQTT / HTTP → Cloud EMS / BMS Platform
Software Compatibility: Plug-and-play synchronization with mainstream third-party systems including Tridium Niagara, Schneider EcoStruxure, and open-source IoT tools like Node-RED or ThingsBoard.
Network Capacity: Supports daisy-chaining up to 32 meters per RS485 bus segment without a repeater, expandable up to 247 nodes with repeaters.

Target Applications
This meter is heavily specified for high-density environments requiring reliable, remote data collection:
EV Charging Piles: Integrated into AC charging stations for accurate user sub-billing and energy tracking.
Commercial & Residential Sub-billing: Installed in multi-tenant apartments, shopping malls, and co-working spaces to isolate individual utility bills.
Solar PV Sub-metering: Utilized to measure real-time active power output from residential and commercial string inverters.
Data Center Server Racks: Mounted inside power distribution units (PDUs) to track rack-level energy metrics and PUE.
