Product details
Technical Requirements for Type II Concentrator of Low Voltage Power User Centralized Meter Reading System of China Southern Power Grid Co., Ltd. (2016 Edition)
Adopting industrial grade Cortex-M3 series controllers and embedded operating systems.
Excellent electromagnetic compatibility performance, able to resist interference from high voltage spikes, strong magnetic fields, strong static electricity, lightning surges, and has strong environmental adaptability.
The uplink communication with the main station adopts wireless public network mode, compatible with communication methods such as GPRS/CDMA/4G.
The downlink communication adopts RS485 bus, carrier, low-power wireless, etc.
The wide voltage range design makes it more reliable and adaptable to the working environment.
New maintenance concept: With powerful configuration capabilities, device parameters can be easily modified locally/remotely, and online software upgrades are supported,
The large capacity motherboard FLASH storage chip ensures convenient storage of various data.
