Note1: The DC voltage measured at the output terminal blocks, for any combination of rated AC voltage,
environment and AC input frequency.
Note2: Output current limits within that the power supply is in regulation (see point 1).
Note3: The maximum steady-state power which the equipment is guaranteed to be able to deliver, while
continuing to meet its other specifications.
Note4: Reduction in output power (or current) as a function of case temperature above the maximum full-
load rated case temperature.
Note5: Amount of change in the DC output voltage (expressed in percentage of rated output voltage) as the
input voltage is varied over its specified range.
Note6: Amount of change in the DC output voltage (expressed in percentage of rated output voltage) as the
load is varied over its specified range.
Note7: Unwanted portion of output voltage harmonically related in frequency to the input line and to any
internally generated switching frequency. The measuring are made directly at the terminal of the power
supply. They take place at rated input voltage and rated output current, with an oscilloscope that has
bandwidth limitation of 20MHz (if not, the common-mode disturbances will distort the results and
reproducibility is not given). In accordance with EN61204, for the low frequency measurement, the normal
single-ended method is adequate. For switching noise a special differential test arrangement is being
used.
Note8: Measures all disturbances (superimposed to output voltage), including the spikes, high frequency
voltage peaks caused, among others, by steep switching slopes. It takes place at nominal input voltage
and nominal output current, with an oscilloscope that has bandwidth limitation of 20MHz for
reproducibility reasons. In accordance with EN61204, for PARD a special differential test arrangement is
being used.
Note9
: Output current (measured at nominal input voltage) at the boundary between continuous and
discontinuous mode operation.
Note10
: Time duration from power supply turn-on until its output voltage goes up into a regulated limit
(Vout = Vnom – 3%).
Note11: Time duration from power supply turn-off until its output voltage goes down into an unregulated
limit (Vout = Vnom – 3%).
Note12: Output voltage ripple (expressed in mVpp) measured when the output is dynamically loaded as
follows: Imin to Imax to Imin (slew rate = 3.2mV/us, duration = 100ms).
