Description

Carrier Wave and GPRS energy meter DCU Data concentrator for remote smart meter reading system

 

 

 

 

• Main Functions:

1. Data Acquisition:Concentrator can collect energy meters’ power data, collection module, and state variables.
2. Data Storage:Concentrator can store real time data, historical daily data, historical month data, meter reading freezing data. It can read and save various meter data according different requirements. The maximum storage is 1024 pcs meters.
3. Data Transmission: Concentrator can keep contact with main station through GPRS and Ethernet, responding main station commands and reporting read data by real time task or timed task
4. Power Cut Date Saved: When concentrator‘s power supply is cut, clock can operate more than 10 years and data will be stored for 30 years. After power supply recovery, data will not be lost and timer operates normally.
5. Event Logging: Both important event and general event will store latest 255 records. Every record includes event type, time and relevant circumstances. 
6. Key User’s Monitor: It can find out abnormal electricity timely and supply analysis basis for anti-stealing.
7. Preferences: it can set various parameters remotely and control power consumption of users’ energy meter.
8. Upgrade : Equipment upgrades access USB, local and remote application upgrade quickly and simply.
9. Equipment Maintenance: Fault diagnosis, overvoltage damage prevention will make sure the equipment stable and reliable.
10. Good Electromagnetic Compatibility: Concentrator can prevent outside conductive transient, magnetic field, static electricity, and lightning’s interference.
