Logic Control

PS_SEATED

TTL logic LOW if power supply is seated into system

connector. This is a short pin. A logic HIGH if the PSU is

removed.

PWR GOOD

Active TTL HiIGH when output is within regulation limits.

AC OK

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.

Temp OK

A TTL logic HIGH, when operating within allowable

temperature range.

PS_INHIBIT/PS_KILL

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.
