Data Concentrator SEA-3700

Low-voltage Centralized Meter Reading Terminal (Data Concentrator) SEA-3700 is an intelligent meter reading device used for data concentrating and data transmission, together with the meter and master station of power utilization information acquisition to constitute AMI system. SEA-3700 concentrator is the intermediate equipment between master station and meters that is installed at low voltage side of the low-voltage distribution transformer. It collects data of all meters within the jurisdiction of this distribution transformer by ways of PLC, RS485 or RF (micro-power wireless), then uploading meter data to master station system by communication modes of PSTN, GPRS/CDMA/3G, Wi-Fi, Optical Fiber Ethernet etc..
