This is a short pin. A logic HIGH if the PSU is removed. PWR GOOD Active TTL HiIGH when output is within regulation limits. DC Input 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 When left open power supply operation will be inhibited. When the power supply is inserted into the system, this pin will be pulled low by the system and turn the power supply on.
