Product Introduction: DDSI183 Type Single Phase Electronic Mode Carrier Meter is used in the long distance centralizing reading-taking system. As an equipment of the system, it could be used to fulfil the electric energy counting for single user, and to communicate the data through carrier wave of power line. It combines many functions such as electric energy measuring, data collecting, transmitting correctly, data preserving and PLC communication. It efficiently and reliably simplifies the structure of low tension power line centralizing reading ?taking system. All of its features meet the standards of GB/T17215-1998 and DL/T698-1999. TYPES & NORMS TYPE:　　　　　　　 DDSI183 LEVEL OF ACCURACY:　1.0 RATED VOLTAGE:　　　220V STANDARD CURRENT:　 2.5(10)A,5(20)A,10(40)A Functions & Features 　>It is stable, accurate and timely so as to realize reading-taking centrally. 　>The reading error is ?0? and the data can be preserved forever if the power is cut off. 　>It can measure active energy accurately and does not need adjustment for a long time. 　>It can automatically and directly connect with superior equipment to prevent irrelevant person to operate it and assure the safety of the data. 　>It has automatic checking function; It can be used to fulfill to long distance power-on or power-off operation and to report abnormal electricity using condition promptly. 　>It can measure electricity consumption, cost and rate according eight different time periods, so there are many options open to consumer. 　>Electricity measuring part adopts special Large-Scale Integrated Circuit to achieve high reliability& simple structure.　 　>It adopts manganese-copper current diverter to turn back the current and it is strong for its practical capacity of overload. 　>It is convenient to install and does not need special line. The cost price is low. Main Technical Parameters: Reference Frequency: 50HZ Starting current: <0.4%IB Power loss: <2W, 5VA Working Temperature: -25°C--55°C Overall Size: 110MM X60MM X155MM
