*) The average efficiency is an assumption for a typical application where the power supply is loaded with
25% of the nominal load for 25% of the time,
50% of the nominal load for another 25% of the time,
75% of the nominal load for another 25% of the time and with
100% of the nominal load for the rest of the time.

Efficiency and losses 1:
Efficiency vs. output current at 48 V typ.; Losses vs. output current 48 V typ.
Efficiency and losses 2:
Efficiency vs. input voltage at 48 V, 10 A, typ.; Losses vs. input voltage at 48 V, 10 A, typ.
