Power Meter 3-Phase 250A 50mA DTSU666-H 020022249-001

The Huawei Smart Power Sensor DTSU666-H is a three-phase current sensor for use in solar systems. The component processes a voltage from 176 to 288 volts and impresses with its very low power consumption of less than one watt. Installation is simple, easy and effortless. If the sensor is built-in, it displays the performance data on the built-in LCD screen and can also work effortlessly. In addition, the Huawei Smart Power Sensor DTSU666-H supports RS485 communication so that it can be read from another location. To do this, it uses the Modbus-RTU communication protocol.

Another great feature of the current sensor is its tremendous accuracy. Voltage measurement accuracy is +/- 0.5%, frequency variation is 0.01 Hz, the sensor measures current, power and energy with a maximum deviation of +/- 1%. This ensures classification in accuracy class > 1. The other technical data must also be observed. The sensor is housed in a housing measuring 100 x 72 x 65.5 mm and weighs 1.5 kg, including wiring. This allows the compact element to be positioned in a space-saving manner. The possible operating temperature is between -25 ° C and +60 ° C, the component withstands a relative humidity of 5% to 95%. The current can be measured up to 250 A. The scope of delivery includes three collapsible current transformers with a cable length of 5 m and a RS485 cable of 10 m.
