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.
TTL level "H" 2.0 V – 5.25 V
"L" 0.0 V – 1.0 V
ST65F-PT
Maximum continuous total DC output power should not exceed650W.
Maximum continuous combined load on +3.3VDC and +5VDC outputs shall not exceed 120W.
Maximum combined load on +12V outputs shall not exceed 650W.
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.
