HUAWEI Smart Power Sensor DTSU666-HW/YDS60-80 – Three Phase Smart Power Meter | Up to 80A | External CTs 1A/5A | RS485 | Class 1 accuracy

Huawei Smart Power Sensor DTSU666-HW/YDS60-80isthree-phase smart electricity meter, intended forprecise energy measurement and managementin solar, industrial and commercial systems.
It is designed to providehigh accuracy (Class 1)and reliable communication throughRS485 interface (Modbus RTU), which makes it completelycompatible with Huawei invertersandSmart Energy Management systems.

The device supports bothdirect measurement up to 80 A, as well as linking ofexternal current transformers (CT) with a secondary current of 1A or 5A, for higher loads.
Thanks tothe LCD display, settings and checking parameters arefast, easy and accurate.
