OUTPUT STABILITY:
The power supply must remain stable for any step load
current change during any combination of input line
voltage and output current loading between and including
rated minimum and maximum values. The output loads may
include capacitance of up to 500 microfarads on the +5V
output, up to 250 microfarads on either +/- 12V output.
OUTPUT TRANSIENT RESPONCE:
For a step load current change of the positive twelve volt
output between rated minimum and maximum values, the
maximum voltage excursion of the positive twelve volt
output shall be 600 millivolts and of the positivre five
volt output shall be 150 millivolts.
OUTPUT HOLDUP TIME

The maximum continuous output is 25.6 Watts.
OUTPUT CURRENT LIMITING
Over current protection wil prevent damage to the power
supply when any output is short circuited continuously
with 100 milliohms or less. Protection circuitry shall
shutdown the output if the continuous output current level
should exceed 200% or more of its maximum output rating.
Damage to the power supply should not occur if operated up
to its maximum over current limit.
