PS_INHIBIT/PS_KILL (B4)
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 high when output is within regulation limits.
A low logic level if the input voltage is within allowable limits. A TTL logic HIGH level, and a 5mS early warning signal
before 12.0 V DC output loss of regulation.
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 supply on only after all other power supply pins have seated.
The output will be enabled when this signal is pulled low, below 0.8 V outputs disabled when pin is driven high or left
open.
