Design and Environmental Specifications<br />
10.3.1 Grounding<br />
The grounds of the power supply output connector pins provide the power return path. The<br />
output connector ground pins are connected to the safety ground (power supply enclosure).<br />
This grounding is designed to ensure passing the maximum allowed common mode<br />
noise levels.<br />
The power supply is provided with a reliable protective earth ground. All secondary circuits are<br />
connected to protective earth ground. Resistance of the ground returns to chassis does not<br />
exceed 1.0 m. This path may be used to carry DC current.<br />
10.3.2 Standby Outputs<br />
The 5 VSB output is present when an AC input greater than the power supply turn on voltage<br />
is applied.<br />
10.3.3 Remote Sense<br />
The power supply has remote sense return (ReturnS) to regulate out ground drops for all output<br />
voltages: +3.3 V, +5 V, +12 V, -12 V, and 5 VSB. The power supply uses remote sense to<br />
regulate out drops in the system for the +3.3 V, +5 V, and 12 V outputs. The power supply must<br />
operate within specification over the full range of voltage drops from the power supply‘s output<br />
connector to the remote sense points.<br />
10.3.4 Voltage Regulation<br />
The power supply output voltages must stay within the following voltage limits when operating at<br />
steady state and dynamic loading conditions. These limits include the peak-peak ripple/noise.<br />
All outputs are measured with reference to the return remote sense signal (ReturnS).<br />

Parameter Tolerance Minimum Normal Maximum Units<br />
+ 3.3 V - 5% / +5% +3.14 +3.30 +3.46 Vrms<br />
+ 5 V - 5% / +5% +4.75 +5.00 +5.25 Vrms<br />
+ 12 V - 5% / +5% +11.40 +12.00 +12.60 Vrms<br />
- 12 V - 10% / +10% -13.20 -12.00 -10.80 Vrms<br />
+ 5 VSB - 5% / +5% +4.75 +5.00 +5.25 Vrms<br />
10.3.5 Dynamic Loading<br />
The output voltages remain within limits for the step loading and capacitive loading specified in<br />
the following table. The load transient repetition rate is tested between 50 Hz and 5 kHz at duty<br />
cycles ranging from 10%-90%. The load transient repetition rate is only a test specification. The<br />
step load may occur anywhere within the Min load to the Max load conditions.<br />
