ISR 4000 series DC power supply - current and fuse selection

[randreescu]

New to this forum.

I've been trying to find the max current for the DC supply for the ISR 4351 so I can select a fuse rating. Seems it came with the PWR-4450-DC and max current is 12A. But there is no or conflicting information in the documentation for the whole platform, especially missing DC current info for this on the data sheet. Can anyone recommend the max operating DC current and fuse rating for this at 48V?

Thanks!
