Huawei
The Huawei Smart Power Sensor DTSU666-H 3P (250A) is a precise and reliable device for monitoring and controlling energy consumption in three-phase systems. It is ideal for integration into modern energy management systems and provides accurate measurements of voltage, current, power, and energy.
The sensor is designed for mounting on a DIN35 top-hat rail and features a RS485-interface with the Modbus RTU protocol for easy integration into existing systems. It operates within a wide temperature range and is suitable for harsh environmental conditions.
Special Features
Precise Measurement
The DTSU666-H offers high accuracy in measuring voltage, current, power, and energy, with a voltage accuracy of ±0.5% and a current, power, and energy accuracy of ±1%. Frequency measurement is performed with an accuracy of ±0.01 Hz.
Energy-Efficient
The sensor has low power consumption of ≤ 1 W and supports sustainable energy management solutions.
Rugged and Reliable
The DTSU666-H is designed for operation in a temperature range of -25 °C to 60 °C and a relative humidity range of 5 %RH to 95 %RH (non-condensing). It features a robust design that ensures a long service life and reliability.
Easy Installation
Thanks to its compact dimensions and the option for easy mounting on a DIN35 top-hat rail, installation is quick and straightforward. The sensor comes with a RS485-cable (10 m) and matching current transformers.
