Technical Features
Supports multiple protocols including IEC61850, the Ministry-approved CDT remote communication protocol, IEC870-5-101 and IEC870-5-103 relay protection communication protocols, DNP3.0, and MODBUS
Adapts to various manufacturers' specialized communication protocols without requiring additional configuration tools during data buffering and distribution
With zero packet loss technology and built-in data buffering, it ensures high-speed, stable transmission
Ultra-wide range power supply
Typical Application
Before system implementation, the communication power supply was connected to the dynamic environment monitoring host via a 485 interface. The central power monitoring system could not directly retrieve data from the communication power supply through this interface; instead, the environmental monitoring acquisition unit buffered and distributed the data, enabling data sharing between dynamic environment monitoring and central power monitoring systems.
