Detailed Product Description

1.General
Three-phase prepayment Watt-hour meter DTSY541/DSSY531 is used to measure active energy by connecting to industrial power supply system. By using the IC card (storage card and smart card), we realize the electrical power system management function of prepayment before consumption to prevent pilfering electricity. Because of using advanced micro-electronics technology to process data, it has high reliability that makes power system management secure.
