* NOTE: The duty cycle will be reduced if the primary input power (AC) is low
or the output voltage (DC) is higher than shown in this chart.
NOTE!
IEC Rating is determined as specified by the International Electro-Technical Commission.
These specifications include calculating an output voltage based upon power supply rated
current. To facilitate comparison between power supplies, all manufacturers use this out-
put voltage to determine duty cycle.
