POWER CONSUMPTION & ELECTRICITY METERING FOR PUBLIC UTILITIESBY OUR CDMA 450 / 2G / 3G / 4G / LTE-M / NB-IOTMODEMS FOR ELSTER® / HONEYWELL®, ITRON®, EMH® AND LANDIS+GYR® METERS

SMART ELECTRICITY METERING MODEMS

Main FeaturesPower consumption metering by wireless modems through the CDMA 450 / 2G / 3G / 4G / LTE-M / Narrow Band wireless networks. Our scalable modem families are having RS232, RS485 (2 or 4-wire) data connection, transparent link.The modem forms part of the AMI (Advanced Metering Infrastructure) of public utility company.Suitable for remote meter readout, meter data download and remote configuration for provider’s request by schedules or on-demand. Our devices are compatible and matching with the electricity meters of the flagship manufacturers.

Benefits• The modem can be fitted into the meter enclosure

and there it can be securely fastened• Design and connectivity meets with brand vendor

meter manufacturer standards• Separated and sealed isolation from meter• Retrofit 2G to 4G migration: we offer our 4G meter
