*) 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.
**) In OFF mode, the unit fulfills the ErP requirements of the European Union.
