The combined output continuous power of all outputs should 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 must meet both static and dynamic voltage regulation
requirements for the minimum dynamic loading conditions. The power supply must meet only
the static load voltage regulation requirements for the minimum static load conditions.
3.3.4 Dynamic Loading
The output voltages should remain within limits specified for the step loading and capacitive
loading specified in the table below. The load transient repetition rate should be tested between
50Hz and 5kHz at duty cycles ranging from 10%-90%. The load transient repetition rate is only
a test specification. The µ step load may occur anywhere within the MIN load to the MAX
load conditions.

3.3.5 Capacitive Loading
The power supply must be stable and meet all requirements, with the following capacitive
loading conditions.

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

3.3.7 Grounding
The output ground of the pins of the power supply provides the output power return path. The
output connector ground pins should be connected to the safety ground (power supply
enclosure). This grounding should be well designed to ensure passing the max allowed
Common Mode Noise levels.
