ADE9000: Detect power line frequency

Hi,

My customer want to know that how to set the output frequency to 0 Hz regardless of the state of the SELFREQ bit,

when the power line frequency is less than 40Hz or no power line detectet,

Thanks and regards,

Makio

    H Makio,

    ADE9000 is designed for energy metering where the frequencies are at 50 Hz and 60 Hz standard power line frequencies. DC measurement is not optimized using this chip.

  • Hi Aheredia,


    Thank you for your quick answer!

    And I'm sorry for the question being too simple.
    I will explain in a little more detail.
    When the frequency measurement range of the ADE 9000 goes out of 40Hz to 70Hz (for example, 40Hz or less),
    the ADE9000 seems to output the set frequency (50Hz or 60Hz output).
    However, even if the power supply is shut off and no output is available, the ADE9000 outputs 50Hz.
    When the power supply is stopped, or when the power supply frequency falls below 40Hz,
    I want to make it the state of "0Hz" (no output).
    Can the ADE9000 realize the above operation?

    Thanks and regards,

    Makio
