1. UWR-3.3/4850-D48A (18-75V input, curve A) and UWR-3.3/4850-D12A (9-36V input, curve A)
will derate curve AA if used over the limited input ranges of 20-60V or 10-30V, respectively.
2. "D48A" models (18-75V input ranges) that derate along curve B will derate along curve BB
if used over the more limited input range of 24-60V.
