The CA168-M is a state-of-the-art smart electricity meter, newly upgraded for utility applications. It integrates high-precision energy measurement with non-wired communication capabilities and flexible billing methods. This single-phase, two-wire watt-hour meter can operate in prepayment or post-credit (post-paid) modes, with the payment mode selectable via commands from the back-end server. Utilities have the flexibility to implement various contractual billing controls tailored to consumer needs.

The CA168-M features a modular design incorporating a plug-in module for data collection and communication. This enables utilities to select the most suitable PLC, RF, GPRS, 3G or 4G LTE cellular network based on local infrastructure conditions, significantly reducing operational costs. Furthermore, upgrades and maintenance are more economical as only the communication modules need replacing, rather than the entire meter unit.

• Payment Mode Flexibility: Toggle between prepayment and post-credit (post-paid) modes via backend server commands.
• Maximum Demand Measurement (Optional): Records peak power consumption (MD).
• Robust tamper protection: Includes magnetic immunity, data retention during power outages and detection of the cover being opened.
• Time-of-Use (TOU) functionality: Supports multiple rates and billing cycles.
• Standard compliance: Adheres to the IEC 62056-21 and DLMS/COSEM communication standards.
• Remote management: Compatible with AMR/AMI systems for remote control and monitoring.
