Overshoot
Overshoot does not exceed 2.0% of any output voltage under the
following conditions: power failure, enabled, disabled, and AC input
cycled on/off. Overshoot is the phenomena where the magnitude of
voltage of an output temporarily exceeds its final or stabilized value.

Load Change Transient
Response
Response
Any DC voltage returns to 1% within 2mS in response to a 25% change
in the load. The +5V output does not vary more than 3% in response to a
25% change in load. The 12V output does not go out of regulation during
a 0.5A change in the +12V load.

Proper Operation
During Dynamic Loads
During Dynamic Loads
The power supply operates properly when subjected to a 10% delta
dynamic load with a 50% duty cycle at all frequencies from zero to 2
MHz, or 2 times the switching frequency of the power supply, whichever
is greater.

Undershoot and Reverse
Voltage
Voltage
With respect to its normal zero reference voltage, no output voltage,
under any normal condition, become of a polarity opposite to its normal
operation polarity (excluding applying an external reverse voltage).

operation polarity (excluding applying an external reverse voltage).
Output Risetime
The +5V output will have a monotonic rise from 2V to 4.75V. The +5V
output will transition from +2V to +4.75V in less than 50mS when loaded
to 37.5A or less.

The +5V output will always be above +3.3V output.
The +3.3V output will transition from +2V to 13.3V in less than 50mS.
The skew in risetime between +5V and +3.3V outputs will be less than 50

The +12V output will transition from +2V to +10.8V in less than 50 mS.
The above conditions will be over the complete input range and load
range, from minimum to maximum load with a capacitive load.
range, from minimum to maximum load with a capacitive load.
Holdover Storage
Output voltage stays within regulation limits for at least 20 msec. from
the last peak of the line voltage cycle after input power is removed. The
power supply does not latch off during an AC line loss condition that is
less than the hold up time.
