STS Split Type Prepayment Gas Meter One Phase GPRS Wireless Communication

Smart Single phase STS Split type keypad prepaid meter DDSY168-S



The Smart DDSY168-S is a dual power source measuring , split type prepayment
electricity meter, completed in BS footprint housing working with a
separate dispay and keypad unit (UIU / CIU). It is an ideal revenue
protection metering tool that can measure grid power and any other
alternative power with no need to add extra components . In duall prepaid
mode, the meter can auto decrypt the recharge code from source and top up
into separate balance .



Major Featureso

20 digit (Standard Transfer Specification) STS encryption
Detection of significant reverse energy (SRE)
IEC62056-21 compliant port allowing for easy data interrogation
Disconnects on overload and no credit
Operate in both prepayment and credit mode hot swap
Programmable load limit and low credit warning
Detection and record tamper event such as cover open, reversal, black-out,
etc.
Split Configuration for Increased Revenue Protection



the meter consists of two parts, the MCU (Meteriing & Control Unit) and UIU
(User Interface Unit). The MCU and UIU is linked via galvanically- isolated
2 -wire communication cable Power line carrier (PLC) and Radio Frequency
(RF) communication module is also aviable on request. The UIU is installed
within consumer's home, while MCU is installed in a meter cabinet away from
consumers.



Utility benefit

Easy connection to User Interface Unit (UIU) for split type applications
RF / GPRS wireless communication with a head-end AMR/AMI server
Time of Use (TOU), multi-tariff, holiday setting.
Advanced load control and disconnection features
