Description
The HWg-PWR 3/12/25 is a smart Ethernet gateway designed for energy monitoring and metering applications. It connects to standard M-Bus meters (EN 13757-2) and provides real-time consumption data via Web, SNMP, Modbus/TCP, and XML.
The device offers data logging for up to 170,000 values and can generate automated energy reports, convert consumption into costs (e.g., kWh to £), and send alerts if values exceed defined thresholds.
With SensDesk Technology integration, the HWg-PWR 3/12/25 can be monitored remotely via PC, smartphone, or third-party SCADA systems. It supports multiple meters from different manufacturers, making it a flexible solution for industrial, commercial, and residential energy management.
