DTS169,the DDS169 three-phase electronic formula the electrical energy table to use the large-scale special-purpose integrated circuit, the surface mounting international advanced technology,the design is unique,the exquisite workm-anship,Commends in the traditional induction type electrical energy compared to,this table has the measuring accuracy high,the stability good,the volume small,the weight light,the power loss is low,the eady solid modern management function expansion,and has lacks instructed,the pulsevehicle postal singal is suitanle management function expansion,and has lacks instructed,the pulsevehicle postal signal is suitable measures 50HZ three-phase the electrical energy. This product for fixedly installs in the room or outdoor electric instrument box uses,adapts is not bigger than under 85%condition in the environment temperature level -20℃~+50℃ relative temperatures to use. This product each performance index conforms to IEC61036 and GB/In17215-2002 standard three-phase electronic formula electrical energy table complete specifcation. | ||||||||||||||||||

Principle of work： | ||||||||||||||||||
| See the picture It will sampling electric current and samping electric voltage of the emulation singnal sends to approproation integrated circuit respctively,wasing enlarged by internal buffer,sending to a multiplication machine,multiplying each other electric voltage and electric current signal,through A/D conversion,will imitate a quantity conversion numerical signal,then electric circuit that pass through cent and drive electric circuit wil electricity quantity signal of pulse blunt the exportation used for driving a pulse electrcity to grow and use electricity index sign. | ||||||||||||||||||

1.Start Under the situation that rule electric current ,the gauge should strart to combine to record in a row.(see form) 2.The potencial move When put on 115% the sun settles pressure,gave or get an electric shock quantiy exportation not less than one pulse when electric current back track mayday flowed. 3.The quantity of electricity The normal electric voltage of work:0.9-1.1 the sum settles electric voltage. Extreme limit of electric voltage:0.8-1.15 the sum settles electric voltage. 4.The temperature condition The temperaure rage:The normal temperature of work:-10-45 . The extreme limit temperature:-40-65 | ||||||||||||||||||
