DESCRIPTION
The PMM1221 is a new-generation three-phase, four-wire multifunction smart electricity meter designed for residential, commercial, and industrial applications. The meter features a modular architecture enabling flexible communication technologies, Advanced Metering Infrastructure (AMI) integration, and secure remote operation.
The meter supports hybrid prepaid and postpaid billing modes, allowing utilities to deploy flexible revenue collection strategies. It provides bi-directional energy measurement, making it suitable for renewable energy and distributed generation environments including solar and hybrid energy systems.
Built for high accuracy, reliability, and long service life, the PMM1221 integrates advanced cybersecurity, remote firmware management, and comprehensive event logging to ensure secure and stable operation in modern smart grid deployments.
APPLICATION
The PMM1221 smart meter is designed for modern smart metering ecosystems where secure communication, accurate billing, and remote management are essential, especially in three-phase power environments.
The meter supports Advanced Metering Infrastructure (AMI) deployments, prepaid utility programs, industrial energy monitoring, and renewable energy measurement applications. With multiple communication technologies and DLMS/COSEM compliance, it can be easily integrated into utility head-end systems, DCUs, and energy management platforms.
Typical applications include:
- Commercial and industrial facilities with three-phase loads
- Residential compounds and multi-unit buildings using three-phase supply
- Utility prepaid smart metering programs (STS compliant)
- Smart grid and AMI infrastructure deployments
- Renewable energy systems including grid-tied and hybrid solar plants
- Sub-metering, embedded networks, and tenant billing applications
