Product Overview:

    DJGJ23-BOOST12 concentrator I (micro power wireless, GPRS/CDMA) is the key device in the low-voltage centralized meter reading system. The concentrator automatically collect and store data of smart meters and acquisition terminals through downlink channel (micro power wireless), and exchange data with mater station through uplink channel (GPRS/CDMA) to achieve the function of remote meter reading.

Product Features:

• Modular design support hot plug of communication module.
• Master-slave working mode.
• With the function of remote time calibration between master station and concentrator, as well as the function of broadcasting time calibration between concentrator and electric meter in the system.
• Self-diagnosis and abnormal information recording capability.
• With functions of automatic calibration, self-diagnosis, abnormal information recording and alarm, data preservation under power off conditions.
• Power outage data storage.
• Concentrator maintenance function.
• Remote upgrade for easy maintenance and debugging.
