Smart Meter – Single Phase – 100A – Huawei

ATTENTION – DELIVERED ONLY TOGETHER WITH AN INVERTER!

The Huawei DDSU666-H Smart Power Sensor is a single-phase current meter designed for inverter connection. It features an integrated LCD display for easy reading and operation. The device supports RS485 communication, allowing remote monitoring of measured values.

Commissioning is fast and secure, guided step-by-step by a digital assistant. Once installed with a single click, the sensor delivers industrial-grade reliability and accuracy.

The device has very low self-consumption (≤1 W). Operating temperature ranges from -25 °C to +60 °C, with relative humidity between 5% and 95%.

Its compact dimensions (100 × 36 × 65.5 mm) allow easy installation on a DIN35 rail. Measurement accuracy reaches ±1% (current, power, energy) and ±0.01 Hz (frequency), corresponding to accuracy class >1.

The package includes a 5 m split-core current transformer (CT) and a 10 m RS485 cable.
