DTSY950/DSSY950 Three-Phase Prepayment Electronic Meter
Summarization:DTSY950/DSSY950 Three-phase prepaid electronic meter uses large-scaled integrate circuit, SMT techniques, world-famous branded long-life components and 5+2 digits LCD or 8 digits LED. It can measure the 50Hz~60Hz three-phase AC active consumption accurately. It meets all the technical requirement of the standard GB/T17215-2002, GB/T18460.3-2001 and some other relative national standards. It can be mainly used in condition of prepayment firstly and consumption later to prepay energy and limit maximum load in order to solve the problem of power company in collecting payment. It has good reliability, wide load, low consumption, high accuracy, and good anti-disturbance performance.Main function and characteristic:1. Can measure the positive and reverse active consumption and accumulate the reverse consumption to positive consumption2. Uses passive photo-electric insulation technique to output passive electronic impulse and LED to show power consumption3. Has the function of customer`s purchasing energy in advance, limiting the maximum load, setting second warning energy and transferring the data by double-directed IC card4. LCD/LED shows the information of energy and meter circularly5. Has different card for each meter to avoid losing energy when card is lost6. Can re-read the information of balance energy, cumulate consumption and total purchasing times7. Can alarm when balance energy is lower than certain value and shut off power when the balance energy reaches zero, can also alarm in condition of over-load8. Can uses one vending system for single-phase and three phase prepaid meter9. Can protect the interface from attacking and store the data for more than 10 years10. Features good reliability, anti-tampering, wide load, low consumption, high accuracy, good anti-disturbance performance and working for long time without calibrationTechnical parameter:1) Accuracy class: class 1 or class 22) Voltage circuit consumption: ≤2W, 6VA3) Reference voltage: 3x110V, 3x380V (for 3P 3W meter), 3x57.7/110V, 3x220/380V (for 3P 4W meter)4) Basic (max. rated) current: 3x1.5 (6) A, 3x 5 (20) A, 5 (30) A, 3x10 (40) A, 3x10 (60) A, 3x15 (60) A5) Limited working temperature: -30 ~ +65°C6) Relative humidity: ≤85%7) Other technical parameter: impulse width 80ms±20ms
