Efficiency typ. 91.5% 92.6% 93.5% at 24V, 10A
Average efficiency *) typ. 91.7% 92.4% 92.4% 25% at 2.5A, 25% at 5A, 25%

Power losses typ. 4.4W 4.9W 6.1W at 24V, 0A
typ. 22.4W 19.1W 16.7W at 24V, 10A
*) 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.
