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
