Stron Smart STS Monophase GPRS communication keypad electricity
meter
STE18-g is used in various intelligent metering applications. It
combines the latest 3DES security encryption technology and modular
communication unit. The meter allows a base current of 5 amperes
while retaining a maximum current of 80 amperes and extended AMR /
AMI features. It is a compact design in a bs8565 standard housing,
and maintains robust RF immunity to withstand 30V / M and IP54
rating, making it able to work in harsh environments.
The instrument works with a plug-in module for DLMS / COSEM
compatible data acquisition and network communication. This modular
design enables utility companies to choose from PLC / RF / GPRS /
3G and 4G LTE cellular data networks at low cost according to local
conditions. Upgrades and maintenance will also become
cost-effective, replacing only the module, not the entire
instrument.
