The fuse didn't blow though.
The fuse is on the input.
But it was rated for 500VA, you'd think that'd mean that for
50Vout, Iout could be up to 10A.

I can see why you'd think so but they don't work that way. The VA
rating is at the nominal '100%' line voltage but many brands won't
even give you that VA number because the limiting factor is current.

Simple.

In that case it should be AMPERE rated NOT VA rated.

IEC basics.
