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;
