z Maximum continuous total DC output power should not exceed 750W.
z Maximum continuous combined load on +3.3VDC and +5VDC outputs shall not exceed 130W.
z Maximum combined load on 12V outputs shall not exceed 648W.
NOTE:
Noise test should be measured with 20 MHz bandwidth frequency oscilloscope. The output terminal
shall add a tantalum capacitor of 10uF in parallel with a ceramic capacitor of 0.1uF.
3.2 Remote On/Off Controlled mode
The PSON# signal is required to remotely turn on/off the power supply, PSON# is an active
low signal that turns on the output power rails. When this is not pulled low by the system,
or left open, the outputs (except the +5VSB) turn off. This signal is pulled to a standby
voltage by a pull-up resistor internal to the power supply.
