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.

The amperage required to blow a fuse does not change because one
changed the operating voltage of a circuit. It is an inline fuse, it
does not care about a voltage ever, and the current required to blow it
is based on the type and construction of the fusing element it uses.

Fuses and breakers are two different animals.

I believe the correct response is 'whoooosh'.
