The combined output continuous power of all outputs shall not exceed 3200W (1600W from
each power supply unit). Each output has a maximum and minimum current rating shown in
below table. The power supply shall meet both static and dynamic voltage regulation
requirements for the minimum dynamic loading conditions. The power supply shall meet only
the static load voltage regulation requirements for the minimum static load conditions.
3.3.4 Dynamic Loading
The output voltages shall remain within limits specified for the step loading and capacitive
loading specified in the table below. The load transient repetition rate shall be tested between
50Hz and 5kHz at duty cycles ranging from 10%-90%. The load transient repetition rate is only
a test specification. The  step load may occur anywhere within the MIN load to the MAX
load conditions.

3.3.6 Ripple/Noise
The maximum allowed ripple/noise output of the power supply is defined in below table. This is
measured over a bandwidth of 10Hz to 20MHz at the power supply output connectors. A 10F
tantalum capacitor in parallel with a 0.1F ceramic capacitor is placed at the point
of measurement.
