1 Phase Single Phase Electricity Meter Two Way Communication Prepayment Meters
The DDSY168-G is a new generation of STS prepayment meter that integrates STS encryption with latest GSM wireless technology, allowing it to be connected to AMR AMI back-end server systems. It offers flexible settings for both metering and payment and user-friendly interface to both the service provider and the end consumers.
Free basic unit, emergency credit, low balance warning is programmable even after the commissioning. The landlords or service providers are allowed to make their own arrear management or debt collection settings into the meter. And consumers are able to check their meter reading as consumption and balance status from time to time via remote access.
In whatever way as it is, the DDSY168-G is a superb electricity dispensing devices and revenue protection tools for both consumers and service providers. Thanks to its broad current range 5(80)Amp, and Un 60% to 130% voltage and a RF immunity withstand of 30Vm, the meter can be installed in very harsh environments.
The meter communication are fully compliant with DLMS/COSEM, making it interoperable with third party applications running on the same protocol.
Main Features
1) Operates in prepayment mode and post payment mode
2) IEC 62056-21 and DLMS/COSEM compliant two way communication
3) Tamper protection: magnetic immunity, data storage in absence of power, cover open trip and alarm
4) Multi-rate, tarrifs on TOU basis
5) Programmable power limit and low credit warning
6) LED consumption indicator
7) 12-key audio feedback keypad
Utility benefits
a) Build-in contactor and GSM slot allows for local and remote load control features
b) Build-in clock sychronize with the real-time of back-end server, providing tariff setting and contractual control features
c) Automated meter reading and remote intrusive control over customers' load
d) Quick and easy installation especially for retrofitting with no need for extra accessories
