Maximum output power varies depending upon the structure of the heat sink attached to the power supply case and upon the velocity of air blown by a
cooling fan against the heat sink. The maximum output power values shown in the table were determined using a 50W standard heat sink(3JR0AB179)
and 1.7m/s air velocity.
