that the test voltage is changing from 2.5KVac to 3KVac. The Test voltage for
the device ADuM1200, ADuM3401 is OK today to Edition 2 IEC61010-1, but moving
forward to Edition 3 IEC61010-1 then we have a problem with UL
certification/approval from Jan 2014. Does Analog devices have any plans to
change the test voltage on the isolators ADuM1200, ADuM3401 to 3KVac ?
Firstly, the ADuM1200 and ADuM3401 do not currently have IEC 61010-1, 2nd Ed
certifications. There are other changes in the 3rd Ed that also will prevent us
from getting 3rd Ed certification. The main issue is a new requirement for
internal clearance and creepage distances for conductors on the same layer
which we don’t meet.
There is some good news, the IEC 61010-1 3rd Ed explicitly allows substitution
of a component-level certification. Several of our customers have successfully
used the VDE-0884 certification which applies to both the ADuM1200 and ADuM3401
