DDSJ949 Single-Phase Anti-Stealing Electronic

A. Summarization
DDSJ949 Single-phase anti-stealing electronic meter uses large-scaled integrate circuit,
SMT technics, world-famous branded long-life components and register against
strong magnetic field. It can get current from double circuits and measure
the 50Hz~60Hz single-phase AC active consumption accurately against tampering of
reversing and by-passing connection. It meets the standard of GB/T17215-20 02 (idt
IEC61036 international standard).Good reliability, anti-stealing, wide load,
low consumption, high accuracy, good anti-disturbance performance and working for
long time without calibration.B. Main function and characteristic
1). 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, high
accuracy, 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. Technical parameter
