Description
This industrial three-phase LoRaWAN® energy meter provides comprehensive monitoring of electrical systems by measuring energy consumption and key power quality parameters. Designed for DIN rail installation, it uses external 1 A or 5 A current transformers (CTs), allowing the meter to monitor a wide range of electrical loads without interrupting the main power circuit.
The meter continuously measures voltage, current, active power, reactive power, apparent power, power factor, frequency, demand and imported or exported energy. This makes it suitable for monitoring factories, commercial buildings, solar installations, utilities, manufacturing facilities and large electrical distribution boards.
Built-in LoRaWAN® connectivity enables long-range wireless communication with a compatible gateway, eliminating the need for RS485 cabling over long distances. Automatic data uploads provide near real-time visibility of electrical consumption, while configurable reporting intervals optimise battery-free operation and network usage. Two pulse outputs are also available for integration with external systems where required.
Integrated with the Sense It monitoring platform, the meter provides live dashboards, historical energy analysis, demand profiling, automated reports and configurable alerts. It is ideal for energy management, cost allocation, preventive maintenance and identifying opportunities to improve energy efficiency across one or multiple facilities.
