Logic Control

PRESENT#

TTL logic LOW if power supply is seated into system connector. This is a short pin. A logic HIGH if the PSU is removed.

PWOK#

Active TTL LOW 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 2 mS early warning signal before

12.0 V DC output loss of regulation.
