Ripple+Noise
Unit
The ripple voltage of the outputs shall be measured at the pins of the output
connector when terminated in the load impedance specified in figure 1. Ripple
and noise are measured at the connectors with a 0.1uF ceramic capacitor and
a 10uF electrolytic capacitor to simulate system loading. Ripple shall be measured
under any condition of line voltage, output load, line frequency, operation temperature.

Note:
1. Total combined output of 3.3V and 5V is 140W.
2. +12V outputs power shall not exceed 504W.
3. When +5V load is 24A, +12V min load is 38A.
4. When +12V load is 42A, +5V min load is 5A.
5. Peak currents may last up to 17 seconds with not more than one occurrence
per minute requirements.

Any overshoot at turn on or turn off shall be less 10% of the nominal voltage value,
all outputs shall be within the regulation limit of section 2.0 before issuing the power
good signal of section 5.0.
2.5 Efficiency
Power supply typical efficiency is 82% under full Load at nominal input voltage of
115VAC or 230VAC.
2.6 Remote on/off control
3. PROTECTION
When the logic level "PS-ON" is low, the DC outputs are to be enabled.
When the logic level is high or open collector, the DC outputs are to be disabled.
3.1 Over-power protection
The power supply will be shutdown and latch off when output power is 110%~160%.
3.2 Over voltage protection
The over voltage sense circuitry and reference shall reside in packages that are
separate and distinct from the regulator control circuity and reference. No single
point fault shall be able to cause a sustained over voltage condition on any or all
outputs.
The supply shall provide latch-mode over voltage protection as defined in Table.
