Project Description
DDSY1598 Smart Prepayment User Interface Unit is designed with robust, reliable and modern features. It can be used to charge a 20-digit numeric code to MCU by encryption protocol STS (Standardized Transfer Specification) or Currency Transfer Specification (CTS), which enabling them to automatically shut off the customer’s power supply in the event of fraudulent manipulation (opening of the terminal cover, etc.) and exceeding of power. It is robust and complies with the Standard Transfer Specification (STS) as well as Currency Transfer Specification (CTS) . When the available credit is exhausted, the customer’s power supply must be immediately disconnected and the meter must not function the “emergency credit”. It is flexible between post payment mode and prepayment mode, and it offers as an optional device to split MCU. With a internal communication module such as cable, PLC or Lora RF, enlarging the scalability to be compatible to Smart Home or AMI features.
