การวัดพลังงาน

Power measuring and insulation monitoring โมดูล for easily measuring various energy information

Rack installation ชนิด energy measuring โมดูล

  • การวัดพลังงาน โมดูล

    QE81WH

  • การวัดพลังงาน โมดูล (multi-circuit)

    QE84WH

  • การวัดพลังงาน โมดูล (three-phase 4-wire product)

    QE81WH4W

  • การวัดพลังงาน โมดูล (multi-circuit, three-phase 4-wire product)

    QE83WH4W

Using only one โมดูล, highly detailed information about electric energy (consumption and regeneration), reactive energy, กระแส, voltage, electric power, power factor, and frequency can be measured. Minimum and maximum values are constantly monitored and 2 ชนิดs of upper/lower limit warnings can be implemented without any programming. The amount of electric power used by output อุปกรณ์s only while ON can be measured.
The power rate during อุปกรณ์ operation and the power rate in takt units can be retrieved. The multi-circuit product allows power to be measured in a smaller space as up to four circuits can be measured with a three-phase 3 สาย product in one slot, and up to three circuits with a three-phase 4-wire product. For example, one unit can be used to measure other loads from the การควบคุม panel trunk.
In addition, the parameters can be set easily with GX Works2 (Version 1.91 V and higher).

  • *1.กระแสไฟฟ้า measurement mode is provided. สูงสุด eight circuits can be measured when measuring only the กระแส value.
  • *2.The separate voltage transformer (QE8WH4VT) is required for the three-phase 4-wire compatible products.

Minimal impact on การควบคุม panel layout

  • By installing the energy measuring โมดูล onto the open slot of the base unit, measuring instrument can be added without changing the layout in the การควบคุม panel.

Allows for detailed power measurement at high ความเร็ว (250 ms)

  • Allows for easy specific energy consumption *3 management by matching the “production information” of the CPU module with the “energy information” of the energy measuring module.
  • Since measured data is automatically collected in a buffer memory at 250 ms, detailed specific energy consumption management is also available.
  • *3.The specific energy consumption is a numerical value displayed by “dividing energy consumption by production volume,” which is one type of index that measures energy productivity. Improving this number leads to improved productivity and energy conservation.

Allows for easy construction of a “visualization” system

  • Allows for easy graphic display of specific energy consumption with a GOT (HMI) installed on the การควบคุม panel at the manufacturing site.
  • Combination with the “high-speed data logger module (QD81DL96)” allows specific energy consumption analysis to be easily performed with a personal computer.
