SDM01-Gen2 COMBO

SDM01 COMBO Gen2

Three-Phase Compact Energy Meter with Clamp CTs

Designed for 3-phase or multiple single-phase circuits, the SDM01 Combo Gen2 energy meter uses three split-core CTs for precise energy tracking. Its seamless integration and rapid response make it ideal for typical HEMS applications - such as export limiting and dynamic load balancing.

- Bi-directional Measurement: Measures power and energy flow for both consumption and generation.
- Easy Installation: Compact 1-module width (18mm) DIN rail design, paired with easy-to-install split-core CTs.
- Fast Measurement: Captures precise RMS power data within 150ms, enabling rapid response for PV, EVSE, and ESS systems.
- Flexible CT Compatibility: Freely match with any official CT to maintain Class 1 accuracy—no factory recalibration required, simplifying field maintenance.
- RS485 Support: Features built-in Modbus RTU wired communication alongside WiFi/Zigbee, perfect for industrial installations.
- Local API: Rich local APIs (HTTP, MQTT, UDP, Modbus TCP, WebSocket etc) to meet diverse integration needs.
