DS1300-3 Datasheet, PDF (2/4 Pages) Astec America, Inc – 1300 Watts 12V Distributed Power System

Logic Control
PS_ON An active low signal that turns on the 12vdc power rail. When this signal
POK
PS FAIL
AC OK
PRESENT
High, or left open, the 12vdc output turn off. The 3.3Vsb output remains on.
Is a power good signal to be pulled low by the power supply to indicate that
all the outputs are within regulation limits of the power supply. (turn-on
delay 100 - 500mS)
In the event of a power supply failure (OVP at any output, UV at any output,
OTP or other electrical failure), this signal shall go to a High state.
High when AC is not OK, Low if AC is OK
Low i f PSU is Present, High if not Present; Pull high in system.
FAN FAIL Low if one or both fans have failed
PS_KILL _{This pin shall quickly turn off the power supply and prevent arching of}
the DC output contacts.
