Hi support team,
I am using the ISO7761 DW-16 together with the UCC12050 to isolate my voltage measurement circuit from my µC-mainboard. The voltage measurement range is to be 1.000VDC. Now I went to a accredited test lab to verify the safety of my system based on EN61010-1. They came back to me saying that a minimum creepage of 10mm and a minimum clearance of 10.5mm according to EN61010-1 is required. The reason is that reinforced isolation is needed and that means the requirements for creepage/clearance need to be doubled.
Now the problem is that both ISO7761 and UCC12050 provide only roughly 8mm creepage/clearance.
What can I do to satisfy this requirement?
