Product Overview:
DJGZ23-BOOST12 concentrator I (narrow band carrier, GPRS/CDMA) is the key device in the low-voltage power carrier centralized meter reading system. It can communicate with various kind of smart electric meter and acquisition terminal with carrier communication function, and realize data acquisition and storage. The downlink channel consists of low voltage power line carrier and RS-485 serial communication channel. The uplink channel consists of GPRS and CDMA communication mode. With modular design, concentrator can support carrier module of major carrier manufacturer and can exchange data with master station and handheld devices. This product is suitable for all levels of power supply companies, public utilities, buildings, residential areas and other centralized meter reading places.
