typ. 20.5 W 18.1 W 13.5 W At 24 V, 300 W (full load)
*) 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.
