And without schematics, it is not safe to power up. It could be anything from 48 to 230V

You are right of course ... but the capacitor for 250V (they grey blocks) are an indicator for 220V ? it makes no sense to use them for 48V I think.

Perhaps , but that would mean they are operating pretty close to their rated voltage anyway it would be better to start at a lower voltage and see if you get a reasonable DC voltage at the other end, rather than start at a higher voltage and let out the magic smoke.
