Revision 2.4
10.2.4.3
Voltage Regulation
The power supply output voltages stay within the following voltage limits when operating at
steady state and dynamic loading conditions. These limits include the peak-peak ripple/noise.
These shall be measured at the output connectors.

Dynamic Loading
The output voltages remains within limits specified for the step loading and capacitive loading
specified in the table below. The load transient repetition rate is 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 minimum load to the maximum
load conditions.

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