Average efficiency
*)
Typ. 94.6% At 25% at 1.25A, 25% at 2.5A,
25% at 3.75A. 25% at 5A
Power losses Typ. 2.1W At no output load
Typ. 6.7W At 48V, 2.5A
Typ. 12.4W At 48V, 5A
Typ. 15.5W At 48V, 6A
*) 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.
