    Hi Anand

    Thank you for your reply.
    According to the customer, it is emission test based CISPR25.

    Do you have information to be shared?

  • In reply to na na78:


    Unfortunately I don't have the CISPR25 data for ISO73xx devices. I've included the CISPR25 data for ISO77xx device below.
    ISO77xx family of devices are superior in isolation and EMC/EMI performance as compared to ISO73xx devices. I would recommend that customer use ISO77xx device in place of ISO73xx device.
    Please do let me know if customer is ok with this data.
