STS Single Phase GPRS Keypad Smart Electricity Meter
The CAM168-G is used for a wide rang of smart metering applications. It combines latest 3DES security encryption technology and modular communication unit. The meter is allowing a basic current of 5 Amp while retaining a maximum current of 80 Amp and extended AMR/AMI functional features. It is a compact design in a BS8565 standard housing and maintains the rugged RF immunity withstand of 30V/m and IP54 rating, allowing it to operate in harsh environments.
The meter works with a plug-in module for DLMS/COSEM compliant data collection and network communications. This modular design enables utility to select from PLC/RF/GPRS/3G and 4G LTE cellular data networks according to local conditions at low cost. Upgrade and maintenance will also become cost-effective by replacing the modules only instead of the entire meter.
