Government First Utility Smart Meter Digital Electric Meter Remote Control
The CA168-M is a high profile newly upgraded new generation of smart electricity meter that combines high precision metrology along with non-wired communication and contractual methodology. It is a single phaes two wires electric Watt-hour meter that works in both prepayment and credit mode. The meter changes the payment mode by the command transmitted from back-end server. Utility can choose from various contractual billing control for consumers.
The CA168-M operates with a plug-in module for data collection and communications . This modular design provides utility free choice of PLC/RF/GPRS/3G and 4G LTE cellular data networks according to local infrastructure conditions, which greatly reduces their operational cost. Upgrade and maintenance will also become economic by replacing the modules only instead of the entire meter.
Main Features
1) Prepayment or credit mode toggle
2) Maximum demand measurement as MD ( Optional)
3) Tamper protection: magnetic immunity, data retention in outage, cover open detection
4) TOU with multi-rate and multi billing cycles
5) IEC 62056-21 and DLMS/COSEM compliant
6) Available for AMR/AMI functionality and remote control from the server side
Key benefits
a) Build in load switch allows for load management on demand and remote
b) Reduce operational and maintenance cost
c) Free to choose suitable communication according to local needs
d) Revenue protection by flexible consumer contractual control
e) Long life time design with easy upgrade features
