Product Description
Intelligent communication multi-channel energy meter
1.Product profile
The intelligent communication multi-channel energy meter is a new type of power monitoring and control energy meter that integrates measurement and recording, energy measurement, alarm output, and network communication functions. This electric energy meter can measure multiple grid parameters such as voltage, current, power, and residual current; Capable of configuring independent RS485 communication interface and 4G dual-mode communication, supporting MQTT communication protocol. It can achieve the monitoring of the operation status of 4 incoming and outgoing lines and branches, as well as the indication of fault status.
