Single Phase DLMS Smart Prepaid Electricity Meter
The STE18-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. And a variety
of communication modules can be selected by users, so that users do
not have to be limited by the communication module, so that the
electricity meter is more diversified. Upgrade and maintenance will
also become cost-effective by replacing the modules only instead of
the entire meter.
