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.
