Huawei DTSU666-HW Three-Phase Energy Meter Smart Power Sensor 80A with 3 Split-Core CTs

The Huawei DTSU666-HW is the three-phase Smart Power Sensor for photovoltaic and storage systems with Huawei SUN2000 inverters. It measures voltage, current, power and power factor on the three phases in real time and counts separately the energy drawn from the grid and the energy fed into it, a figure that is essential for self-consumption management.

It is installed on a 35 mm DIN rail between the utility meter (or the main protective devices) and the loads of the building, and it communicates with the inverter via RS485 Modbus-RTU. It performs direct measurement up to 80A per phase; for higher currents, external current transformers with a 1A or 5A secondary are used. In the standard supply configurations it is combined with three YDS60-80 split-core CTs.

Key features

Direct measurement up to 80ACovers most three-phase installations without CTs; for higher currents, external current transformers are used.
Input for external CTsSecondary channel compatible with current transformers having a 1A or 5A secondary, to extend the range on commercial installations.
Split-core CTs includedThe typical supply includes three YDS60-80 split-core current transformers with cable, which can be fitted without cutting the conductors.
Accuracy class 1Voltage ±0.5 %, current and power ±1 %, frequency ±0.01Hz.
3P3W and 3P4W networksWorks on three-phase networks with and without neutral, with line-to-line voltage up to 499V AC.
RS485 Modbus-RTUConnection to Huawei SUN2000 inverters with the supplied RS485 cable; own consumption below 1.5W.
