SSC frequency technology is adopted with micro processor which shall handle the data transfer. The metering system is connected with power supply administration center through L.V. power lines, which transfers the data quick, accurate and reliable. Main function: 1. Measurement of single phase active power. 2. SSC large frequency technology is adopted to achieve the power line wave carrier communication. 3. Automatic record and control according to address code. 4. To record the parameter semi-automatically through CMRI 5. RS 485 special line and L.V. power line frequency wave carrier communication methods Salient Features: 1. High accuracy: 1.0 class. 2. High reliability: long operating life 3. Collect and record the data of the meter correctly on time 4. Low power consumption, tamper proof and easy to install 5. Register displays actual consumed power 6. Non-volatile memory with big capacity is adopted to memorize the data under the no-load condition for 20 years
