Smart Prepayment Meter
DDS1079-1 Split Din-rail Single Phase STS Prepayment Meter

DDS1079-1 is  a  DIN  Rail  installation metering  and  control  unit  used  in  one phase  two  wire  power  networks.

Combined  with  CIU,  it  works  as  keypad prepayment  meter complying with STS standard.

  • Prepayment, compared with traditional electricity meter, which solving the charge difficulty;

    STS standard, an open safety transmission standard.

    Enclosed design, avoiding the outside attack due to the open vulnerable interface;

    Split type, including meter and CIU, communication through an embedded PLC(built-in);

    Payment information is transmitted by TOKEN code, extensible various payment means;

    Built-in relay, supporting various flexible control modes;
