Why you should choose a Smart Power Sensor DTSU666-H from Huawei now.

The Huawei Smart Power Sensor DTSU666-H is a three-phase current sensor for use in solar systems. The component processes a voltage of 176 to 288 volts and impresses with a very low power consumption of less than one watt. Installation is simple, easy and straightforward. Once the sensor is integrated, it displays the performance data on the built-in LCD screen and can also be operated effortlessly. In addition, the Huawei Smart Power Sensor DTSU666-H supports communication via RS485, meaning it can also be read out from another location. It uses the Modbus-RTU communication protocol for this purpose.

Another outstanding feature of the current sensor is its enormous precision. The measuring accuracy of the voltage is +/-0.5 %, the fluctuation in frequency is 0.01 Hz, and the sensor measures current, power and energy with a maximum deviation of +/-1 %. This ensures classification in accuracy class >1. The other technical data should also be noted. The sensor is housed in a casing measuring 100 x 72 x 65.5 mm and weighs 1.5 kg, including cabling. This allows the compact element to be accommodated in a space-saving manner. The possible operating temperature is between -25 °C and +60 °C, the component tolerates a relative humidity of 5 % to 95 %. Current can be measured up to 250 A.

The scope of delivery includes three hinged current transformers with a cable length of 5 m and an RS485 cable with a length of 10 m.
