PC4713-W-485 Three-Phase WiFi + RS485 Smart Energy Meter
PC4713-W-485
Open-protocol three-phase smart energy meter with WiFi (HTTP/MQTT/Modbus TCP) and RS485 (Modbus RTU) communication. Direct-to-cloud or local reading with 50ms data refresh — no third-party cloud required.
Overview
PC4713-W-485 helps you monitor the amount of electricity Consumed and Produced in your three-phase power system by connecting the clamps on to the power cables. It is also compatible with split-phase and single-phase. The real-time data can be reported directly to your cloud server or be read locally without going through a third-party public cloud.
