Type I Concentrator
DJTD23-HX3200
Dedicated to automated data collection and intelligent meter reading in low-voltage power systems
Product Description
The DJTD23-HX3200 series concentrator, referred to as Type I concentrator, is developed using a 1GHz quad-core high-performance core board and a unified operating system software platform. It integrates GPRS/4G/5G/Ethernet remote communication technology, carrier/micro-power wireless/dual-mode heterogeneous local communication technology, and high-precision energy metering technology. Adopting modular design and object-oriented design concepts, it is a new-generation centralized meter reading terminal product featuring advanced technology, stable performance, reliable operation, and easy maintenance. It is suitable for power companies at all levels, public utilities, public buildings, residential communities, commercial complexes, and trade markets where centralized multi-meter data collection is required but data density demands are low. This product complies with the State Grid Corporation of China 2022 technical specifications and DL/T698.45 Energy Data Acquisition and Management System Part 4-5: Object-Oriented Interoperable Data Exchange Protocol.
