STS DLMS Prepaid Single Phase Electricity Meter For Mini-grid Project With LoraWAN

The LoRaWAN DIN-Rail Single-Phase Electricity Meter offers a compact and efficient solution tailored for mini-grid applications, perfect for installations where space is at a premium. This meter integrates a built-in LoRaWAN wireless module, facilitating smooth data transmission to a gateway via LoRaWAN. Subsequently, the gateway relays this information to a server through GPRS/4G or Ethernet connections. With an impressive communication range of up to 5 kilometers in open areas, a single gateway can manage up to 20,000 meters simultaneously, making it highly scalable for expansive networks.

Featuring a clear LCD display, the meter provides real-time monitoring of energy consumption and other critical metrics. This user-friendly interface simplifies energy management, enhancing operational efficiency and ease of use for system operators.

Engineered with safety and reliability in mind, the meter functions effectively within a voltage range of 70% to 120% of the nominal voltage (Un), ensuring stable performance even under fluctuating conditions. For enhanced connectivity, the meter also includes an infrared optical port, promoting seamless integration with other smart devices for advanced automation and energy optimization, thereby supporting the development of smart grids.

To ensure continuous operation during power outages, the meter is equipped with a built-in lithium-ion battery, providing reliable backup power to maintain functionality and data integrity.

In essence, the LoRaWAN DIN-Rail Single-Phase Electricity Meter stands as an advanced, versatile, and efficient tool for managing energy usage in smart grid environments. It delivers robust communication capabilities, supports energy optimization, and easily integrates with other smart technologies, positioning it as an ideal choice for contemporary energy management systems.
