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.
