Output Power/Currents
The following table defines power and current ratings for the 550-W power supply. The
combined output power of all outputs does not exceed the rated output power. The power
supply meets both static and dynamic voltage regulation requirements for the minimum loading
conditions.
Output Voltage
Notes:
1.
Maximum continuous total output power will not exceed 550 W.
2.
The maximum continuous total output power capability increases at lower ambient temperatures at a rate of
3.3W/degree C up to 600 W with a 30 degrees C ambient temperature.
3.
Maximum continuous load on the combined 12V output will not exceed 40A at 45 degrees C, ramping up to
44 A at 30 degrees C.
4.
Peak load on the combined 12V output will not exceed 48 A.
5.
Peak total DC output power will not exceed 600 W.
6.
Peak power and current loading is supported for a minimum of 12 seconds
7.
Combined 3.3V and 5V power should not exceed 160 W.
2.2.4.10
Power On Loading
The power supply operates at lighter load conditions when the system first powers on. Under
these conditions, the voltage regulation limits are relaxed. Power on loading and voltage
regulation requirements are defined in the following tables.
Time duration is 1 second during power on.
