DS650DC-3/DS850DC-3 Data Sheet

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.

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.
