The three-phase Huawei DTSU666-H Smart Power Sensor 3-phase meter provides current measurement in the 0 - 100 A range. The DIN35 rail-mounted device communicates via RS485 interface and includes three current transformers.
The three-phase Huawei DTSU666-H Smart Power Sensor 3-phase meter is used for precise monitoring of electrical grid parameters. The device is designed to work in 3P3W and 3P4W systems at a phase voltage of 176 to 288 V AC. Data exchange occurs via an RS485 interface using the Modbus-RTU protocol at a baud rate of 9600 bps. The meter's maximum power consumption does not exceed 1 W, and it is installed on a standard DIN35 rail.
