Static Prepayment Watt-hour Meter
DTSY541 Three-phase prepayment watt-hour meter is used to measure active energy in industrial power grid. The meter used IC card (Memory card and smart card) to realize prepayment function before consumption to prevent electricity pilfering. By adopting advanced microelectronics technology to process data, it is a highly reliable meter that makes power system management secure.
