Product Description

I-type Concentrator

Introduction:
DJT(G)Z(H/J)-SFJ395 series I-type concentrator adopt digital communication technology, embedded technology, computer software and hardware technology to collect, analyze and process power demand side information. It adopts high-speed 32-bit embedded micro-controller and embedded operating system based on the controller, communicate with the master station by 4G/GPRS or Ethernet, which is a small-model smart collection terminal that integrates telemetry,  remote measurement, meter reading function, statistics and wireless communication. It has functions of electric energy measurement, data storage, remote data transmission by various communication methods, powerful event recording and alarming, power quality monitoring, and carrier centralized meter reading. This concentrator can be widely used in the monitoring of low-voltage distribution automation systems.
The product has the characteristics of powerful functions, easy to use, stable operation, convenient maintenance, high reliability, large storage capacity and high cost performance, which can well meet the application needs of users.
