ADE7878 alternate

Hey guys. I need to replace one IC that has been used in one of the projects. The IC is ADE7878 Energy metering IC that can be used to supply 3 phase active power to the controller for processing.

However, I am looking for its alternate, and I find in the product page for other similar parts and I found ADE9000 to be suitable. Since I am new to analog devices products and energy metering systems, it would be good if you guys give me some suggestions.

I appreciate your suggestions.

Regards,

  • Hi ,

    The ADE9000 is our advanced multi-phase energy metering solution. The ADE7878A is the enhanced version of ADE7878.

    What kind of application that you want to develop?

    What current sensor that you want to use?

    One of the ADE9000 features that is not available in ADE7878 is a power quality measurements, do you need it?

    • Enables implementation of IEC 61000-4-30 Class S
    • VRMS ½, IRMS ½ rms voltage refreshed each half cycle
    • 10 cycle rms/12 cycle rms
    • Dip and swell monitors
    • Line frequency—one per phase
    • Zero crossing, zero-crossing timeout
    • Phase angle measurements

    What do you need to know?

    Best source of documentation would be the datasheet and technical reference manual.

    Kind Regards,

  • Hi Nanda, thanks for you reply.

    Yes I am interested in power quality measurements, but that's an added feature, And I want to know that the features that ADE7878 provides, can those features/specs be achieved by using ADE9000. If that is the case, I can go for ADE9000 with added feature of power quality measurement, but if that is not the case, I will go for ADE7878A.

    I want to have the experts advice.

    Thanks 

  • And one more thing I would like to add, actually I need to add a rogowski coil in the project, and as per my knowledge, I just did an overview of the datasheet, and it says that we can integrate rogowski coil with ADE9000. This is in fact the deciding factor.

  • Yes ADE9000 supports Rogowski coil like the ADE7878A. The biggest difference is whether you need the power quality measurements or not in your application.
