Stron Smart STS Monophase GPRS communication keypad electricity
meter
The STE18-G is used for a wide range 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.
