——Product Introduction——


The DTU function in the power distribution terminal can be flexibly combined through software configuration.

The DTU function module monitors the operation and fault information of line voltage, line current, zero sequence current, equipment status, etc. Complete remote signaling, telemetry and remote control functions to realize real-time monitoring of distribution automation.Its protection function realizes the on-site detection and removal of line faults.

The communication management module has a variety of communication interfaces and a variety of standard communication protocols. In addition to the terminal’s internal data management function, it can also forward the energy meter, PLC and DC screen data in the power distribution room or opening and closing station, and communicate with the master station system through a standard unified interface to complete data transmission and other functions.

The DTU distribution terminal adopts a distributed design mode. The powerful software and hardware configuration functions not only meet the real-time requirements of DTU, but also realize the data storage and recording function.

At the same time, it can also realize the independent configuration function of line microcomputer protection, successfully solving the measurement and control, protection, communication compatibility and coexistence issues, to achieve the purpose of simplifying the types of station equipment.
