## Summary description

HUAWEI DTSU666‑HW is a 3‑phase smart power sensor for accurate measurement of power and energy. It provides Wi‑Fi connectivity for remote data access and integration with monitoring systems. Designed for industrial and commercial electrical installations, it enables consumption tracking, anomaly detection and supports energy management and billing workflows.

## Long description

HUAWEI DTSU666-HW is a 3-phase smart power sensor designed for accurate measurement of electrical power and energy in industrial and commercial installations. The device measures voltage, current, active and reactive power, power factor and energy consumption across three phases and provides Wi‑Fi connectivity for remote data access and integration with building management and energy monitoring systems. Compact and suited to DIN-rail mounting, the sensor supports continuous monitoring for consumption tracking and anomaly detection while enabling data export for energy management and billing workflows.
Advantages
The sensor delivers precise three-phase measurement with error margins suitable for operational monitoring and energy accounting. Built-in Wi‑Fi connectivity enables remote access to live and historical data without additional wiring, simplifying installation in retrofit and new-build scenarios. The device offers stable performance under typical commercial electrical conditions and integrates with monitoring platforms through standard communication protocols. Its compact form factor and DIN-rail compatibility facilitate mounting in distribution panels and electrical cabinets.
Suitable for
Energy monitoring and reporting in commercial buildings
Power consumption tracking in industrial facilities
Integration with building management systems and energy platforms
Remote metering and billing workflows
Anomaly detection and preventive maintenance programs
Key specifications
Measurement: three-phase voltage and current, active and reactive power, apparent power, power factor, and cumulative energy
Connectivity: Wi‑Fi for remote data access and integration
Installation: compact module suitable for DIN-rail mounting in distribution panels
Accuracy: designed for precise operational monitoring and energy accounting (industrial/commercial grade)
Data access: real-time monitoring and historical data export for energy management
Operating environment: typical commercial and light industrial electrical conditions
How to use
Install the device on a DIN-rail inside an appropriate electrical cabinet and connect the three-phase voltage and current inputs according to the wiring guidelines supplied by the manufacturer. Configure Wi‑Fi parameters using the local interface or setup application to enable network access. After connectivity is established, integrate the sensor with the chosen monitoring or building management platform using supported communication methods. Use the platform to visualise live values, configure data logging intervals, and export reports for energy accounting or billing.
Usage recommendations
Place the sensor in a protected indoor environment away from direct moisture and excessive heat. Ensure correct phase identification and secure current input connections to maintain measurement accuracy. For integration with third-party systems, verify compatibility with your monitoring platform and apply appropriate network security settings when enabling Wi‑Fi access.
