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. 
 

 

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.

DC output rise time is less than 20 mS at nominal line and full load. 
 

DC +5V output maintains at least 12mS after power off  which hold within para 3.1  under 
115V/60Hz and 230V/50Hz  condition.
