SDM01 Smart Energy Monitors with Split-core Current Transformers SDM01 Smart Energy Monitors with Split-core Current Transformers Datasheet Product Description SDM01 smart energy monitor is a monitoring device that consists of a 18mm-width (1MW) monitor installed at DIN rail and three split-core current transformers (CTs). Functioning as a professional 3-phase energy meter, it accurately measures real-time voltage, current, power and energy data, with wireless and/or wired communication options available for data transmission. Bi-directional measurement: Measure power and energy flow in both consumption and generation. Real-time monitoring: Monitor key electrical data like Voltage, Current, and Power in real time. Easy installation: Monitoring module requiring only 1MW at DIN rail and associating with compact split-core CTs Versatile communication: A wide range of communication options including Wi-Fi, Zigbee, BLE, Modbus etc. Local Automation: Enable local UDP broadcasting and HTTP requests, ideal for DLB1) and zero export for HEMS2) Real-time home energy monitoring and metering Energy-usage monitoring for small business3) Electrical monitoring for commercial buildings4) and infrastructures Electrical monitoring for industry energy efficiency projects Dynamic load balancing and zero export to grid with solar generation5) 1) DLB: Dynamic Load Balancing 2) HEMS: Home Energy Management System 3) Small business: Café, restaurant, shop, renting apartment etc. 4) Commercial buildings: office, hotel, shopping malls etc. 5) In addition to whole-home energy monitoring when being installed at the main incoming circuit, the real-time monitoring of bi-directional power flow can provide input for DLB and minimizing grid export from solar generation Smart Energy Monitors
