1. AC INPUT
Table 1 AC Input Line Requirements
Power factor correction (PF)>0.90 at full load.
1.2 Inrush current regulation
The power supply must meet inrush requirements for any rated AC voltage, during
turn on at any phase of AC voltage, during a single cycle AC dropout condition,
during repetitive ON/OFF cycling of AC, and over the specified temperature range
(Top). The peak inrush current shall be less than the ratings of its critical components
(including input fuse, bulk rectifiers, and surge limiting device).
Note:
1.Voltage tolerance is requied at main connector and S-ATA connector(if used).
2.Output transient response tested DC voltage regulation range +5V±5%, +12V±5%,
+3.3V±5%, +5Vsb±5%, -12V±10%.
1.Maximum continuous total DC output power should not exceed 550W.
2.Maximum continuous combined load on +3.3V and +5V outputs shall not exceed 140W.
3.Maximum combined current for the +12V outputs shall be 45A(540W).
4.Maximum peak total DC output power should not exceed 600W.
5.Peak power and current loading shall be supported for a minimum of 12 second.
6.When +12V is load to 25A , -12V minimum load is 0.02A.
