Product Overview:

Communication unit (broadband carrier) product is a data transmission unit which uses power line as communication medium and broadband communication technology to realize power carrier communication function. According to application type, it can be divided into three types: TXZX13-BGSK communication unit (single-phase/broadband carrier), which is mainly suitable for single-phase collector I and single-phase watt-hour meter, TXZX13-BGTK communication unit (three-phase/broadband carrier). Mainly applicable to three-phase watt-hour meter; TXZX13-BGJK communication unit (concentrator I/broadband carrier), mainly applicable to concentrator I terminal.
