Products description

A. Summarize     

DDS950 Single-phase electronic meter (guide way installation type) uses large-scaled integrate circuit, SMT technics, world-famous branded long-life components and 5+2 digits wide-temperature LCD. It can measure the 50Hz~60Hz three-phase AC active consumption accurately. It meets all the technical requirements of the standard GB/T17215-2002 (idt IEC61036 international standard) and some other relative national standard. Good reliability, wide load, low consumption, highly accuracy without calibration for long time, anti-tampering and good anti-disturbance performance.

B. Main function and characteristic

1. Can measure the positive and reverse active consumption and accumulate the reverse consumption to positive consumption.

  2. Uses passive photo-electric insulation technique to output passive electronic impulse and LED to show power consumption.

  3. Good reliability, wide load, low consumption, high accuracy without calibration for long time, anti-tampering and good anti-disturbance performance.

   4 .LCD shows information directly.

   5. Rail type installation and conveniently for setting.
