-
- The whole machine has low power consumption, modular software design, and perfect protection function configuration.
- The standard 4U aluminum alloy chassis structure, front plug-in design, production, installation and maintenance is convenient, very suitable for the special installation requirements of the distribution network.
- The main control, telemetry, remote control, remote communication and power supply boards are independent of each other and adopt modular design, which can be matched at will. The upgrade and expansion of various modules are convenient and will not be affected by each other.
- Centralized operation can simultaneously monitor 4 sections of bus and 12 circuits, perform real-time data processing on all monitored objects, monitor current and voltage imbalance, effectively remove faulty lines, and reduce power failure range. Under the double-layer structure, it can effectively monitor the operation status of the 24-circuit line.
- Large-capacity non-volatile memory holds a variety of records and data, including protection events, remote shift SOE, daily extremes, telemetry data whole point records, and so on. The storage capacity of all records and data shall not be less than 30 days.
- Two-level watchdog protection and dynamic self-test function ensure the working reliability of the device.
- Each line is equipped with four sets of fixed value, which can easily switch different fixed value groups according to different working conditions of the line. Remote/local modification of fixed values and parameters is supported.
- It has two Ethernet interfaces and four RS232/RS485 communication interfaces. Optional external GPRS/CDMA communication module.
- Support CDT, DNP3.0, 101, 103, 104 and other communication protocols.
