Delay from PSON# de-active to PWOK being de-asserted.
Delay from loss of AC input to de-assertion of ACOK#.
Delay from output voltages within regulation limits to PWOK asserted at turn on.
Delay from PWOK de-asserted to 12 Vdc or 5.0 Vsb dropping out of regulation limits.
Duration of PWOK being in the de-asserted state during an off/on cycle using AC or the PSON# signal.

PSON #
The PSON# signal is required to remotely turn on/off the power
supply. PSON# is an active low signal that turns on the +12 Vdc
power rail. When this signal is not pulled low by the system, or left
open, the +12 Vdc output turns off. The Vsb output remains on.
This signal is pulled to a standby voltage by a pull-up resistor
internal to the power supply. The power supply fan(s) shall operate
at the lowest speed.
PWOK# (POWER GOOD)
PWOK is a power good signal and will assert HIGH when the
outputs are within the regulation limits. PWOK will be pulled LOW
by the power supply to indicate when either output falls below
regulation limits or when AC power has been removed for a time
sufficiently long so that power supply operation is no longer
guaranteed. The start of the PWOK# delay time shall be inhibited
as long as the +12 Vdc output is in current limit or the 5.0 Vsb
output is below the regulation limit.

The +12 Vdc output only from the power supply shall be disabled
if the PSKILL input is high and V Standby will continue to be
provided, outputs may be enabled if this signal is low. The power
supply includes a pull up to disable all outputs if this signal is open.

AC INPUT PRESENT INDICATOR (ACOK/L)
The ACOK signal is used to indicate presence of AC input to the
power supply. This signal shall be connected to Vsb through a
resistor on the host system side. A logic “Low” level on this signal
shall indicate AC input to the power supply is present. A Logic
“High” on this signal shall indicate a loss of AC input to the power
supply.
