Intel® Server Chassis H2000 Family TPS Power Sub-System Table 20. Voltage Regulation Limits Parameter +12VSTB +12V Min +11.40V +11.40V Nom +12.000V +12.000V Max +12.60V +12.60V Unit Vrms Vrms Tolerance ±5% ±5% 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. Table 21.

Load Slew Rate 0.25 A/sec 0.25 A/sec Test capacitive Load 20 F 2000 F 3.3.5 Capacitive Loading The power supply must be stable and meet all requirements, with the following capacitive loading conditions. Table 22. Capacitive Loading Conditions Output +12V +12VSTB Min Max Units 500 25,000 F 20 3100 F 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.
