.i. Summary
DJGZ23-ES3402 concentrator is the most important part of low voltage power line carrier concentrative meter reading system, which collects the electricity consumption's need information and analysis and handle with the modern communication technology, intercalation technology, computer software/hardware technology, low voltage power line carrier technology, etc. It can read the meter by low voltage carrier, automatically make the report, communicate the collection of analog, etc.
DJGZ23-ES3402 concentrator can conveniently revise the equipment parameters in local or distance and support online upgrade at local or distance. The board- FLASH storing ship with high capacity can guarantee all kinds of data storage conveniently. It is made of ABS waterproof and inflaming retarding material, with the framework of hanging at wall. It can conveniently install because of its light weight.
DJGZ23-ES3402 concentrator can greatly meet user's application demand like the monitoring of distribution and substation, meter reading at distance, preventing electric larceny with the characters like strong function, simple use, stable operation, convenient protection, high reliability, high storing capacity, good opening, and high performance price ratio, etc.
