2. Maximum peak total DC output power should not exceed 572W.

3. Peak power and current loading should be supported for a minimum of 1 second.

4. +3.3V, +5V and +12V DC output voltage should be within Figure 1 cross loading

range to meet regulation.

5. Ripple and Noise measuring with an oscilloscope with 20 MHz bandwidth in

Figure 1 cross loading range. Output should be bypassed at the connector with

a 0.1uF ceramic disk capacitor and a 10uF electrolytic capacitor to simulate

system load.The length of ground wire on probe should not longer than 40mm,

if a Non - differential type of scope was used.

2.1 CROSS REGULATION

The +5V & +3.3V combined load and +12VDC load shall remain within the defined

in section 2.0 over cross load combinations shown Figure 1:

2.2 HOLD-UP TIME: 16ms (minimum)

Test Condition: Full load. AC input 115V or 230V, 47Hz.

2.3 LOAD TRANSIENT RESPONSE (STEP LOAD)

Step load changes up to 60% (12V) and 30% (3.3V and 5V) of full load, while

other loads remains constant within the rating. The load waveform shall be a

square wave with the slope of the rise and fall at 1.0A/usec and the frequency

shall be from 50Hz to 10kHz. The DC output voltage will stay within regulation

of ±5% during the step load changes.
