Single-Phase LCD/LED Display Prepayment Electronic Meter

Place of Origin	China

Summarization:DDSY949 single-phase LCD/LED-display prepaid electronic meter uses large-scaled integrate circuit, SMT techniques, world-famous branded long-life components and 5+2 digit LCD or 6 digit LED display. It can measure the 50Hz~60Hz single-phase AC active consumption accurately. It meets the standard of GB/T17215-2002. It can be mainly used in the area of pre-paid consumption. The energy bought firstly and then used with the limitation of maximum loading so as to solve the problem in charges. It features good reliability, wide load, low consumption, high accuracy, and good anti-disturbance performance.Main function and characteristic:1) Can accumulate both direct and reverse consumption accurately2) Has separate LED photo-emitter and electrical impulse outputs to show power consumption3) Can prepay energy consumption; limit the maximum load, secondary alarm for certain balance, data is transferred by encrypted IC card4) LCD can display the recurrent information of consumption and meter or LED displays the recurrent information of consumption and meter by pushing the button5) Each meter has its own card; the energy information will never lose even though the card lost6) Can read information such as balance energy; accumulate consumption and total buying times7) Alarm for the balance energy and over load8) The energy selling system can be used for both single phase and three phases9) Has the port of anti-attacking to store the data for more than 10 years when powered off10) Good reliability, anti-stealing, 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, 10VA3) Reference voltage: 110V, 120V, 220V, 230V, 240V4) Basic (max. rated) current: 2.5 (10) A, 5 (20) A, 5 (30) A, 10 (40) A, 10 (60) A, 20 (80) A, 5) Limited working temperature: -30 ~ +65°C6) Relative humidity: ≤85%7) Other technical parameter: impulse width 80ms±20ms producing area:China
