Precautions for operating this DC-DC converter:
-For fanless operation de-rate the output of the 3.3 and 5V rails by ~35% or
ensure PSU surface temperature should not exceed 65C, whichever comes first.
-Combined and sustained output should not exceed 65% of total power or or
ensure PSU surface temperature should not exceed 65C, whichever comes first.
-Input current should not exceed 8A. For current higher loads, we suggest using
a 2x2 mini-FIT JR as an input connector.
-Peak load for individual rails should not exceed 60 seconds.
-For long life operation, PSU surface temperature should not exceed 65C.
