Three Phase Electronic Prepayment Meter (DTSY541)

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. 2.Basic functions 2.1 Bi-directional active energy measurement 2.2 LED display or LCD display 2.3 Pulse output with optical-coupling isolated 2.4 Over-load alarm 2.5 Precaution alarm 2.6 Power down alarm 2.7 Purchase reminding 3.Technical Data Standard: IEC 61036-2000 Service Lifetime: 10 years Accuracy Class: Class1, Class2 Working Temperature: -30C +65C Working Voltage Range: 0.7 1.2Un Power Loss: Less than 2W or 10VA Outline Dimension L x W x H: 289x170x96 mm Installation Dimension L x W: 274.5x145 mm Weight: Approx.2.8kg
