The Huawei DTSU666-HW Smart Power Sensor is a three-phase electricity meter designed for use in photovoltaic energy systems. The device operates within a voltage range of 176–288 V and has an extremely low power consumption of less than 1 W.
Installation is quick and straightforward. Once the sensor has been integrated into the system, the power data is displayed on the built-in LCD screen, which also allows easy local operation.
The Huawei DTSU666-HW Smart Power Sensor supports RS485 communication, enabling remote data reading. Communication is carried out using the Modbus RTU protocol.
One of the sensor’s key features is its high measurement accuracy. Voltage measurement accuracy is ±0.5%, frequency accuracy is 0.01 Hz, while the maximum measurement deviation for current, power, and energy is ±1%. The device therefore has an accuracy class of greater than 1.
The meter has a compact housing with dimensions of 100 × 72 × 65.5 mm. It weighs 1.5 kg, including the wiring, allowing space-saving installation.
The operating temperature range is -25°C to +60°C, and the device operates reliably at a relative humidity of 5–95%.
Current can be measured directly up to 80 A. For currents above 80 A, indirect measurement using current transformers (CTs) is required.
The package includes the meter and a 10 m RS485 cable.
