Huawei DTSU666-H Energy Meter (3-phase, 250 A, RS485)

The three-phase Huawei DTSU666-H energy meter is designed for semi-indirect measurement of grid parameters in 3p4w systems. The device communicates via the RS485 interface and is mounted on a standard TH DIN rail.

The Huawei DTSU666-H smart power sensor enables precise monitoring of energy consumption in three-phase installations. The device operates on the basis of semi-indirect measurement using 250 A / 50 mA current transformers. The meter is equipped with a clear LCD display for easy direct reading of operating parameters. The use of a Class II protection housing (double insulation) ensures a high level of operational safety.
