iCoupler ADuM524x CTI-value

Hello,

I use an iCoupler ADuM5242 in a device that is currently under test at UL.

Regarding the safety clearances, the UL inspector does not accept the CTI value of 175V described in the document. He says it was not tested under UL and so, he cannot accept the described value issued by the document.

The application has got on the lower side a circuitry that is connected to SELV. The iso side is connected to 250V at the most.

Is there any argument I can express that the ADuM5242 is suitable nevertheless?

Thanks for your help.

Regards, Andreas
