You should find a PSU that meets your spec...there are loads of them, literally loads for you...
try
digikey, Newark, RS, farnell as well as mouser.
Also, meanwell, Recom etc etc
try "open frame power supply"
"open frame switch mode power supply"
"switch mode power supply"
even just "power supply"
etc etc
You have found the perfect DC-DC converter for your application, with the exception that no, you really have not.
On an electrical vehicle, whether an auto, a forklift or a bicycle, if an intermittent connection appears during regenerative mode, what is called a "load dump" situation occurs.
The voltage will skyrocket well above even the maximum normal. 2 to 3 times above nominal maximum is the industry standard.
The converter you choose should be derated for at least 20% above your continuous maximum, with transient capabilities at least twice that.
You may counter with: "hey I've tested it and it works fine" response. And my question will be, yes but for how long? Will the converter protect itself and shutdown, or will the magic smoke come out?
yes its normal for a PSU to draw about a watt in idle, its because it maybe has a linear regulator to supply bias current to the control circuitry.
Expensive psu's use more speical circuitry to cut down no load power.

it says vin=75vdc Absolute maximum, so i wouldnt go above that. (ok it says you can go up to 100vdc but only for 0.1 second)
You are referring to the SM-Bus parameter? The datasheet (DS_Q48SC12025_06022015) however says absolute maximum rating 100V for 100 ms. Did the module ever work with rated voltage? Presume you wired the enable input.What surprises me is that the default over voltage value is 110 volts. I really thought it would handle the 82 volts.
