Three Phase STS IC Card Prepaid Electricity Meter


The DTSY150-C is a new generation of prepaid electricity meter that integrates high precision metrology features along with security encryption and wireless communication technologies. The meter works with a plug-in module for 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. Upgrade and maintenance will also become cost-effective by replacing the modules only instead of the entire meter.



1. Maximum demand measurement and load profile record at preset intervals.

2. Tamper protection: magnetic proof, data retention in outage, cover open detection

3. TOU with multi-tariff and multi billing cycles

4. Plug& play communication modules

5. IEC62056-21 and DLMS/COSEM compliant

6. Prepared for AMR/AMI functionality

Utility Benefits:

1. On demand and remote load management

2. Reduce operation and maintenance costs

3. Choose suitable communication according to local needs

4. Revenue protection by flexible consumer contract control

5. Long life time with easy upgrade features
