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.
Product Features:
Collect real- time electric meter data, and daily zero point freeze data of each meter.
Data storage capacity not less than 32M. Capable to save the daily zero point freeze data, zero point freeze data at the end of the month and integral point data of key users.
Set the master-slave working mode through remote uplink communication channel of the master concentrator to communication with mater station, and realize the data exchange between master concentrator with its cascaed slave concentrator and the master station.
With functions of automatic calibration, self-diagnosis, abnormal information recording and alarm, data preservation under power off conditions.
Built-in ESAM security certification module. Following Technical Specification for Safety Protection of Power User Consumption Information Acquisition System , to protect the safety of key data and sensitive information.
