DDSJ949 Single-Phase Anti-Stealing Electronic Meter

Place of Origin	China

A. Summarization DDSJ949 Single-phase anti-stealing electronic meter uses large-scaled integrate circuit,SMT technics, world-famous branded long-life components and register againststrong magnetic field. It can get current from double circuits and measurethe 50Hz~60Hz single-phase AC active consumption accurately against tampering ofreversing and by-passing connection. It meets the standard of GB/T17215-20 02 (idtIEC61036 international standard).Good reliability, anti-stealing, wide load,low consumption, high accuracy, good anti-disturbance performance and working forlong time without calibration.B. Main function and characteristic1). Can accumulate both direct and reverse consumption accurately.2). Has separate LED photo-emitter and electrical impulse outputs to show power consumption.3). Features good reliability, anti-tempering wide loading, low consumption, highaccuracy, good anti-disturbance performance and working for long time without calibration.4). LED shows the exceptional consumption against tampering of reversing and by-passing connection.5). Can offer RS485 and infrared communication according to customer's requirement.C.
