isolater Maximum Continuous Working Voltage

Hi

I have a question , Maximum Continuous Working Voltage.

This is ADM2484E DS.

It's written DC Voltage Basic Insulation 1066Vpeak , Reinforced Insulation 529Vpeak.

ADE7913 DS is , DC Voltage Basic Insulation 1173Vpeak . not have Reinforced Insulation.

And ADUM2211 is , DC Voltage 1130Vpeak.not have Reinforced Insulation.

How many is ADE7913 and ADUM2211  DC Voltage Reinforced Insulation ?

It has DC Voltage Reinforced Insulation which is about ADM2484E's Reinforced Insulation 529Vpeak ?

Best regards

    Hi HOD,

    We can help you to pick the best selection of parts to fit the customer's application. Please provide more details:

    • What is the customer's application? Energy metering?
      • On the front end there is an energy metering IC (ADE7913), and then on the back end there is a RS-485 comms (ADM2484E)?
    • Does the customer require basic or reinforced insulation?
    • What voltage levels are present in the customer's application? AC or DC, or both? And what levels?

    Best Regards,

    Richard

  • Hi

    Thank you for your answer.

    What is the customer's application? Energy metering?

    →Application is Energy Charge battery system.

    On the front end there is an energy metering IC (ADE7913), and then on the back end there is a RS-485 comms (ADM2484E)?

    →RS485 is used in a connection of each module.

    Does the customer require basic or reinforced insulation?

    →Customer requires  Reinforced Insulation.

    What voltage levels are present in the customer's application? AC or DC, or both? And what levels?

    →Customers wants Reinforced Insulation 529Vpeak and 5000 V rms isolation voltage for 1 minutes.

        When it's the same specification as ADM2484E, it's no problem.

    Best regards

    Hi HOD,

    For the ADM2484E see Table 4:

    This part is certified to VDE 0884-10 with 849V peak reinforced working voltage.

    The part also has a 5000 V rms rating per UL1577.

    For the ADE7912/7913 see Table 2:

    These parts are certified to VDE 0884-10 with 846V peak reinforced working voltage.

    The part also has a 5000 V rms rating per UL1577.

    Best Regards,

    Richard
