Understand that the DCP01 Series is good for 1KVrms for up to 60 seconds per the UL1950 test only. However, is the reason behind the continuous voltage change to 60VDC across the barrier due to the fact that life testing is no longer conducted for this part? The old Burr-Brown specification said that the 1KV continuous voltage was based on life test data. I've inserted the old specification. Is this the reason why additional clarity into the specification was provided in the specification sheet?3173.DCP0124.pdf
