The DDSY150-C is used for a wide range of prepaid applications. It combines latest STS(Standard Transfer Specification) with 3DES security encryption technology. 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 a 30K/m and IP54 rating, allowing it to operate in harsh environments.                                   

The meter works with a plug-in module for data collection and network communications. This module-design enables utility to select from PLC/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.
