I didn’t see a converter part number in the initial post, hence my confusion. This makes much more sense.
The blunt-force way to do this is to buy one, pull the screws, and look. We’ll see what Rob’s inquiry returns, but my experience suggests that cracking a seal and looking for oneself can be a very good way to get important information.
Regarding paralleling of outputs, the datasheet indicates presence of a current limiting protection mechanism.
In conjunction with the V-I characteristics of an external OR-ing diode, the parasitics of the interconnect conductor(s) and/or any deliberately added ballast resistance, it should be possible to make multiple units play nicely together. Some supplies are made to work as a team, others can be made to work as a team. Where there’s a will, there’s a way.
Regarding input fusing, suggestions of the sort found in the datasheet for the supply in question aren’t written in stone and may come with unwritten caveats. I’d be wary of subjecting a 4A rated fuse to repeated 500A surges if nuisance tripping is to be avoided.
I’m having trouble accessing the information offered. The email response feature frequently results in such disconnects, as well as unintentional exposure of personal information contained in email signatures. Interaction via the forum site for followup dialogue limits these adverse effects.
