HUAWEI POWER METER DDSU666-H 3-PHASE
The Huawei Smart Power Sensor DTSU666-H is a three-phase current sensor for use in solar power systems.
The component processes a voltage of 176 to 288 volts and impresses with a very low power consumption of less than one watt. Installation is simple, easy and effortless.
Once the sensor is integrated, it displays the performance data via the built-in LCD screen and can also be operated effortlessly via it.
In addition, the Huawei Smart Power Sensor DTSU666-H supports communication via RS485, so it can also be read out from another location. It uses the Modbus RTU communication protocol for this purpose.
Another outstanding feature of the current sensor is its enormous precision.
