Overview
The performance indicators are in line with the IEC62056 related requirements.
Concentrator uses power line carrier and is an important part of RF concentrated meter reading system concentration, in the integration of modern digital communication technology, embedded technology, computer hardware and software technology, low voltage power line carrier and RF technology. It can analyze, process and save the grid information (i.e., ac analog), energy consumption information, tamper information and leakage information collected from watt-hour meter and others equipment, and at the same time, it can be sent to master station through GPRS/CDMA communication software.
Concentrator can modify equipment parameters in local/remote conveniently, has reliable security measurement, to prevent unauthorized personnel from setting parameters. Concentrator supports online upgrade of local/remote software; main board FLASH memory chip with the large capacity is able to save daily historical meter-reading data in one year(365 days) of 1000 system equipment.
Concentrator can meet the application requirements of distribution transformers monitor, remote meter reading, anti-tamper monitoring alarm, leakage monitoring alarm.
