Adopting low-power NB-IoT communication modules, it features wide coverage and no need for additional wiring. With an accuracy class of 1.0, it meets national metering standards. It supports bidirectional metering, adapting to self-used distributed photovoltaic scenarios. It has built-in overcurrent and overvoltage protection modules to improve power use safety. Users can query power consumption data remotely via APP and receive power outage and leakage alarm information, solving the pain point that users cannot master real-time power consumption status. It also supports remote firmware upgrading and is compatible with mainstream power marketing system interfaces.
The device has dimensions of 188mm × 120mm × 75mm and a weight of 1.2kg. It supports a rated frequency of 50Hz, with a pulse output constant of 1600imp/kWh. The standby power consumption is ≤0.5W, and it works in a humidity range of 5%~95%RH (no condensation). It supports remote firmware upgrade, compatible with DL/T645 and MODBUS communication protocols, and can be seamlessly connected to existing power management platforms. The built-in LCD display clearly shows power consumption, remaining power, and other data, meeting the daily inquiry needs of users and property managers.
It is suitable for urban residential buildings, rural self-built houses, distributed household photovoltaic grid-connected systems, and single-phase power consumption scenarios of small shops. It helps power meter reading staff complete monthly meter reading without visiting households, reducing on-site operation risks and improving meter reading accuracy and efficiency. It also assists property managers in real-time monitoring of resident power consumption, optimizing property energy management services.
