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.
