Power Line Carrier STS Prepaid Meters Tariff Control Smart Meters For Electricity
The DDSY168 equiped with G3-Power Line Carrier (PLC) communcation unit is able to interact and communicate with an AMR / AMI head-end server system (HES) for smart metering fucntions such as automatic meter readout, remote disconnect and reconnect meters, parameter settings, etc. The meter is a one phase two wire , neutral missing operatable( optional) STS compliant prepayment meter, finished in a compact BS footprint mounting housing of IP54 protective rating and a surge arrestor sustaining up to 13kV lightening. It is used for a wide rang of metering applications in harsh and grid unstable environments.
The DDSY168 supports IEC compliant accuracy metrology and at the same time DLMS/COSEM protocol compatible communication . The meter adopts power line carrier of G3 standard communication for data exchange and automated meter reading. It provides the utility users and service providers an efficient and low operational cost data collection and revenue protection tool.
Features
1) Operate in STS prepayment and post-payment mode
2) Measurement of significant reverse energy (SRE)
3) IEC62056-21 compliant optical & RS485 port
4) Trips on no credit and overload
5) Surge safe and low voltage operateble at -60%~+30% V
6) Programmable power limit , free basic unit and repayment policy
7) Anti-tamper features: cover open, reverse connection, magnetic field detection, neutral missing etc
User benefits
a) Easy and quick installation especially for retrofitting due to BS footprint using existing wires
b) Smart metering features offers real-time data and remote intrusive load control
c) Time synchronization allows for multi-rate and Time of Use (TOU) tariff plans and holiday settings
d) Low operational and inventory cost
