DC Input ARTESYN DS650DC-3/ DS850DC-3 Distributed Power Bulk Front-End Connector input shown Advanced Energy s Artesyn DS650DC and DS850DC series DATA SHEET bulk front end power supplies are the DC-input versions of their DS650 and DS850 AC-input counterparts. Mechanically Total Output Power: identical to the AC versions, these products allow system 650 - 850 Watts operation from a Telco style 48 Vdc input. Rated at 650 and +3.3vdc Stand-by Output 850 watts respectively, the power supplies provide a choice Standard Telco input range -39 V to -72 VDC of 12 V, 24 V or 48 V output. Each model also provides a 3.3 V or optional 5.5 V standby output. Standard features include active current sharing, internal ORing FETs and an EEPROM for storing service data to facilitate efficient field replacement. 2 An I C communication interface is provided for FRU EEPROM data.

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. 2 advancedenergy.com
