The Huawei DTSU666-HW current sensor is a three-phase smart current sensor designed for use in solar energy systems. It processes voltages from 176 to 288 volts with extremely low power consumption, below one watt. Installation is simple and easy. Once integrated, the sensor displays performance data through the built-in LCD screen and can be easily operated through it.

The sensor supports communication via RS485, allowing for remote reading. It uses the Modbus RTU communication protocol for this purpose.

A remarkable feature of the sensor is its high accuracy. The voltage measurement accuracy is +/-0.5%, frequency variation is 0.01 Hz, and the measurement of current, power, and energy has a maximum deviation of +/-1%. This ensures that the sensor is classified in accuracy class >1.

Other technical information includes: the sensor is housed in a case measuring 100 x 72 x 65.5 mm and weighs 1.5 kg, including cables. This allows for space savings due to the compact component. The operating temperature ranges from -25 °C to +60 °C, and the material withstands relative humidity from 5% to 95%. Current can be measured up to 80 A (direct connection) and above 80 A (indirect connection with CTs).
