ARTESYN DS1050 Distributed Power Bulk Front-End Advanced Energy s Artesyn DS1050 series bulk front end DATA SHEET AC-DC power supply accepts a wide range 90264 Vac input and provides a main 12 V output plus a 3.3 V or 5 V standby Total Output Power: output. Rated at 1,050 watts it is an 80 Plus Gold supply with 1050 Watts a high half-load efficiency of 92%. Housed in an industry +3.3 or 5.0 Vdc Standby Output standard 1U x 2U rack-mounting package, the power supply Wide Range Input Voltage: is ideal for space-constrained applications. This series comes 90 - 264 Vac in two airflow versions dc-connector to ac-connector and vice versa.

This is a short pin. A logic HIGH if the PSU is removed PWR GOOD (C3) Active TTL high when output is within regulation limits. AC OK (B1) 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. PS INHIBIT/PS KILL (B4) 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. PS ON (A1) 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. 2 advancedenergy.com
