Description

The Huawei DTSU666-HW Smart Power Sensor is a single-phase energy metering device designed for residential and commercial applications. It provides Class 1 measurement accuracy with ±0.5% voltage/current accuracy and ±1% power/energy accuracy, enabling real-time monitoring and analysis of electricity consumption.

The device features an LCD display for easy setup and status checking, with low power consumption of ≤1.5 W. It communicates via RS485 interface using Modbus-RTU protocol, supporting multiple baud rates (4800–115200 bps). The unit mounts on a DIN35 rail and measures 100 × 72 × 80 mm, weighing less than 0.5 kg including cables.

Designed for 3-phase/4-wire or 3-phase/3-wire power grids with input voltage of 90–500 Vac, the sensor supports current measurement up to 80 A (expandable with external current transformer) and line voltage measurement up to 1000 Vac (with external potential transformer). Operating temperature range is −25 to +60 °C. Includes 10 m RS485 cable and 100A current transformer (CT).
