The reinforced isolation of CAT-2 300V EN61010-1 3rd for ADuM1301/1401BRWZ

Dear Sir/Madam, maybe Dave C.

Question:

Do you have the evidence document of the reinforced isolation of CAT-2 300V EN61010-1 3rd?

Otherwise can you recommend another i-coupler fit for the reinforced isolation of CAT-2 300V EN61010-1 3rd?

Story:

We are confirming your following models to our Certification Organization that they can use to put on the part of reinforced and isolated circuit as CAT-2 300V EN61010-1 3rd.

ADuM1301BRWZ

ADuM1401BRWZ

So we submitted your the one of Certification Body(CB) that I enclosed here to our Certification Organization and confirmed. Then we got the following comment from him.

We cannot confirm from CB.

1) The distance of internal isolation

2) The isolation thickness

3) The tested value by high voltage

Therefore Certification Organization guy could not be passed your ADuM1301BRWZ and ADuM1401BRWZ as reinforced isolation of CAT-2 300V EN61010-1 3rd.

Thanks, Kaos
