+5V	50	mVp-p
+12V	120	mVp-p
-12V	120	mVp-p

Definition

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, or operation temperature.

Ripple/Noise voltage test circuit

• Overshoot Any overshoot at turn on or turn off shall be less than 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.
• Efficiency Power supply’s typical efficiency is 82% under full Load at a nominal input voltage of 115VAC.
• Remote on/off control 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.

PROTECTION

Over-power protection The power supply will be shut down and latch off when the output power is 110%~160%.

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.

Output	Minimum	Nominal	Maximum	Unit
+12 VDC	13.4	15.0	17	Volts
+5 VDC	5.74	6.3	7.5	Volts
+3.3 VDC	3.76	4.2	4.8	Volts

TIMING

The signal timing drawing is a reference for signal timing for main power connector signals and rails.

PS-OK Timing Sequence

• T2: Rise time (0.1ms~20ms)
• T3: Power good turn on delay time (100ms~500ms)
• T4: Power good turn-off delay time (1ms min)
• T5: Rise time (10ms max)

+12 VDC	40%	–
+5 VDC	30%	–
+3.3 VDC	30%	–
