CL730S24 is the latest high-performance smart meters launched by CLOU, designed for residential and commercial electricity usage in three-phase grid environments.
As the core devices of the new generation AMI (Advanced Metering Infrastructure), these meters integrate cutting-edge modular technology and support multiple communication methods such as PLC (Power Line Carrier), RF (Radio Frequency), and cellular communication. They can be flexibly configured according to different application needs to achieve stable and efficient data interaction.
The products strictly adhere to the DLMS international standard, ensuring secure and reliable communication with strong compatibility. Additionally, the CL730S24 innovatively support seamless switching between STS prepayment and post-payment modes, and can operate stably regardless of whether a communication module is installed. This provides users with highly flexible electricity management solutions, aiding in energy efficiency optimization and operational cost control.
