Huawei DTSU666-FE Three-Phase Meter Smart Power Sensor 100 A Ethernet Modbus-TCP
The Huawei DTSU666-FE is the three-phase Smart Power Sensor with a Fast Ethernet interface, designed for photovoltaic systems, storage systems and electric vehicle charging stations. It measures voltage, current, active and reactive power, power factor and imported and exported energy on three-phase and single-phase networks.
It is mounted on a 35 mm DIN rail in the board at the connection point and transmits the data via an Ethernet port with Modbus-TCP protocol, a useful solution when laying an RS485 bus all the way to the inverter is awkward or too long. The built-in LCD display allows local reading of the quantities and configuration of the network parameters.
Key features
Communication over an Ethernet networkFast Ethernet port with Modbus-TCP protocol: the meter connects to the site LAN instead of a dedicated serial bus.
Three-phase and single-phase measurementCan be used on 3P4W and 3P3W networks and on a single phase, with bidirectional counting of energy drawn and fed in.
100 A capacity with CTsMeasures up to 100 A per phase; beyond the direct capacity, external current transformers are used.
Accuracy class 1Accuracy compliant with class 1 for active energy.
Built-in LCD displayShows voltage, current, power and energy and allows the communication parameters to be configured.
Low-consumption board formatMounting on a 35 mm DIN rail with self-consumption ≤ 2 W and operation from −25 °C to +60 °C.
