Just realized that was DC-DC. For those we use the Traco TMDC 60-4824
or TMDC 60-4848.

are approx $300 for the pair. The nice thing is they have a temp probe

A lot of power substation control equipment is high voltage DC (100-300 VDC).

I don't think it is a misprint, I have seen other high-voltage input DC:DC 
converters (you can find some from Sager/Powergate), but they're much rarer 
than things which have a top-end input voltage maximum of around 76VDC...    
Really curious what sort of weird industrial applications are relatively low 
wattage at a couple hundred watts load for a device, and need that kind of 
input.
