Logic Control
PS_SEATED
PWR GOOD
TTL logic LOW if power supply is seated into system
connector. This is a short pin. A logic HIGH if the PSU is
removed.
Active TTL HiIGH when output is within regulation limits.
AC OK
Temp OK
PS_INHIBIT/PS_KILL
A LOW logic level if the input voltage is within allowable
limits. A TTL logic HIGH level, and a 5mS early warning
signal before 12.0v DC output loss of regulation.
A TTL logic HIGH, when operating within allowable
temperature range.
This signal is connected to a short pin on the PSU
When left open power supply operation will be inhibited.
When the power supply is inserted into the system, this
pin will be pull low by the system and turn the power sup-
ply on only after all other power supply pins have seated.
