Huawei Single Phase Smart Power Sensor – DDSU666-H

The Huawei Smart Power Sensor DDSU666-H is a single-phase current sensor for connection to the inverter. It is easy to operate and read out data via the built-in LCD screen. In addition, the component supports communication via RS485, so that the measured values can also be evaluated elsewhere. Commissioning of the current sensor for PV systems is simple and safe – the digital wizard guides you through the integration process. Once installed by one-click, the component meets the highest demands. The DDSU666-H smart power sensor is designed for use at industrial level and is particularly reliable.

The technical data of the sensor is also convincing, for example, its own power consumption is less than one watt – so the device works without consuming much power itself. The possible operating temperature is specified as -25 °C to +60 °C, the relative humidity can be 5 % to 95 %. The dimensions of 100 x 36 x 65.5 mm show that this is a compact component. It is mounted on the DIN35 top-hat rail. The input voltage is 176 VAC~288 VAC (phase / N). In operation, the Smart Power Sensor DDSU666-H achieves a measurement accuracy of +/-1 % (current, power and energy) and +/-0.01 Hz (frequency). The current sensor thus belongs to accuracy class >1.
