Product Description

Branch measurement unit collector and sensor

1.Product Introduction
The operation and distribution integration terminal is composed of a main control module and an expansion module through bus communication. The main control module integrates functions such as secure encryption, human-computer interaction, backup power supply, and local communication. The expansion module includes remote communication module, broadband carrier communication module, branch monitoring module, remote communication module, remote control module, RS-485 module, etc.
The integration terminal of operation and distribution supports communication with management and monitoring systems such as metering automation main station, electric energy meter, temperature and humidity sensor, etc. It can realize the access of distributed energy related equipment and monitor and manage distributed energy. It can support the access of electric vehicles, charging stations, energy storage devices, and user devices, and can collect information, monitor the status, calculate the load, control the load, report load events, and manage orderly electricity consumption of the access devices. Support analysis and diagnosis of local user topology based on electricity data algorithms, and have abnormal alarms. Support functions such as data collection and processing, data query and reporting, event recording, parameter setting and querying, demand response and load control, local display, software and hardware security protection, etc.
