Huawei Smart Power Sensor DTSU666-HW/YDS60-80 Energy Meter, 80 A Three-Phase

The Huawei Smart Power Sensor (DTSU666-HW/YDS60-80) is a three-phase energy meter for accurate, real-time monitoring of electrical consumption. It offers Class 1 measurement accuracy (±0.5% for voltage/current, ±1% for power/energy) and supports current measurement up to 80 A. The device mounts on a DIN35 rail and includes an LCD display for easy configuration and readout.

Communication is via an RS485 interface using the Modbus-RTU protocol, enabling integration with Huawei's Smart Energy Management System to monitor solar installations and energy storage systems. The operating temperature range is −25 °C to +60 °C, and power consumption is minimal at ≤1.5 W. A 10 m RS485 cable is included.
