Single Phase Smart Energy Meter with STS Prepaid Keypad, GPRS/4G module​

The CA168-CS23 represents a cutting-edge, upgraded version of the smart energy meter that combines precise metering capabilities with wireless communication and control features based on contractual principles. This meter is designed for single-phase, two-wire systems and supports both prepayment and credit modes. The payment method can be modified remotely through commands from a central server. The device provides comprehensive metering information, including voltage (V), current (A), power factor (PF), total consumption, balance, and the last five successfully entered tokens.
