Huawei DTSU666-H Smart Power Sensor 3-phase meter

The Huawei DTSU666-H Smart Power Sensor 3-phase meter is designed for monitoring electrical parameters in photovoltaic installations. It enables the control and limitation of electricity export from the PV system to the grid, as well as monitoring the self-consumption level. Installing the meter provides real-time viewing of parameters such as: voltage, current (total and per phase), active and reactive power, frequency, positive energy, reverse energy, and many more. All data is presented on the LCD display. Measurements up to 250 A are carried out using the current transformers included in the set. The meter communicates via the RS485 interface and is designed for TH DIN rail mounting. Full technical data can be found in the manufacturer's data sheet. Product with the same functionality can be supplied by the manufacturer and used interchangeably under the following indices: DTSU71 DTSU666-H 250A/50mA DHSU1079-CT YDS60-C24 Detailed differences between the meters can be found in the Official Information Letter from Huawei.
