Description

The Eastron SDM530-LR is a carrier-grade Three-Phase LoRaWAN Energy Meter engineered for comprehensive power analysis and active load control. Capable of handling up to 100A through a direct connection, it eliminates the need for external current transformers in many industrial and commercial setups. The meter tracks a full suite of electrical parameters, including Active Energy (kWh), Current (A), Voltage (V), Power Factor, and Demand. A standout feature of the SDM530-LR is its internal relay, which allows facility managers to remotely disconnect or reconnect the electricity supply via LoRaWAN commands or set automated safety shut-offs based on pre-defined alarm thresholds.

Smart Grid Management & Control

Bi-Directional Metering Fully supports import and export energy measurement, making it an ideal solution for solar PV installations and renewable energy monitoring.

Class C LoRaWAN Efficiency Operating as a Class C device, the meter is always listening for downlink commands, ensuring near-instantaneous execution of remote relay triggers.

Industrial Smart Metering Scenarios

• Property Management: Prepaid electricity solutions for commercial tenants with remote shut-off for non-payment.

• Industrial Automation: Monitor machinery power quality and consumption while protecting assets via threshold alarms.

• EV Charging Stations: High-precision billing and load balancing for 3-phase electric vehicle charging infrastructure.
