ELECTRICITY POWER AND ENERGY CONSUMPTION METERING FOR PUBLIC UTILITIES BY OUR CDMA 450 / 2G / 3G / 4G / LTE-M / NB-IOTMODEMS FOR ELSTER® / HONEYWELL®, LANDIS & GYR® AND ITRÓN® ELECTRICITY 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 data 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.

Advantages• Our modems can be fitted into the meter enclosure

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

meter manufacturer standards• Separated and sealed isolation from meter• Retrofit 2G/3G to 4G migration: metering modems

with same outfit, backward compatibility• Power supply from the metrology (AC or DC)• Optional surge protection from 4kV up to 12kV• Remote meter readout („Push” or „Pull” method)• IEC 62056-21 protocol / DLMS option• Can be operated from private networks with NAT:

the modem connects to Head-End-System (HES)• Scheduled data sending or triggered by an alarm, or

SMS triggering• Immediate alarm notification• Remote FW updates• Configuration tool

(downloadable)• Implementation for

automated energy metering systems

Design & construction• RS232/RS485 (upon request), transparent link• Design & connectivity satisfy Elster® / Honeywell®

(WM-E1S®) and Landis & Gyr® meters (WM-E1SL®)• It can be installed under the terminal cover and there

fastened securely• Surge protection: 4kV to 12kV• AC power from the meter

Software & configuration• Immediate alarm notification• WM-E Term® tool or optional DMSet® software• “Push” data transmitting (Ftp / IEC 62056-21 push

or by SMS trigger)• Scheduled data sending

or triggered by an alarm
