Part Number: AMC1100
I have a design that uses the AMC1100DWV to measure mains voltage. I am having difficulty getting it through IEC61010-1. As far as I can see it is approved for use for edition 2 of the standard but not edition 3. I am aware of white paper slyy055 but our test house says this is just an opinion and they need a certificate.
Do TI intend to get this part certified to IEC61010-1 3rd Ed and if so when?
In reply to Tom Hendrick:
The AMC1100 is listed under VDE 0844-10, so that should be enough to satisfy your test house. The certificate is here:
It seems that the AMC1100 provides basic insulation but not reinforced insulation, so we can't use it. The unit it is going in is earthed so I don't understand why it need reinforced insulation but that's what I have been told.
In reply to Michael Forster:
Your AC Mains voltage should be the driving factor for determining basic versus reinforced isolation levels. If you used the AMC1100 in the DWV package, the AMC1301 would be a drop in replacement and is qualified to reinforced voltage levels.
It seems not. The problem seems to the DTI, Distance Through Insulation, which is given as >= 0.027mm but for IEC/EN/UL/CSA 61010-1 3rd edition Clause 220.127.116.11.2, 0.4mm is required, or Clause 18.104.22.168.4 for multiple layers of thin-film.
Your slyy055 white paper says -
TI has initiated the certification process of all its products to help end-equipment manufacturers meet these requirements. VDE and TÜV have completed the certification process for many of TI’s isolation devices and several product families are CSA-certified now, with the remainder scheduled to be certified
Is the AMC1301 now certified to edition 3 or is it scheduled to be?
Hi Mike, The SLYY055 document was put together by one of the guys here at TI who deals with the digital isolators, devices like the ISO7421. Some of those isolators have been tested to certain aspects of the IEC 61010 standard, but the AMC1100 and the AMC1301 have not been. The parts should still be qualified through section 14 though at the component level. If it's OK with you, I'll contact you directly and we can talk more about your specific application.
