ARTESYN DS450-3/DS550-3 Distributed Power Bulk Front-End Advanced Energy s Artesyn DS450 and DS550 series bulk DATA SHEET front end AC-DC power supplies accept a wide range 90264 Vac input and provide a main 12 Vdc output, plus a Total Output Power: 3.3 Vdc standby output. Rated at 450 watts and 550 watts 450 - 550 Watts respectively, the DS450 and DS550 have a typical full load +12 Vdc Main Output conversion efficiency of 84%. Standard features include +3.3 Vdc Standby Output active current sharing, internal ORing FETs and an EEPROM Wide Range Input Voltage: for storing service data to facilitate efficient field replacement. 90 - 264 Vac An I2C communication interface is provided for the FRU EEPROM data.

When the power supply is on and running normal P6 is low. When the power supply is off, either due to -PS ON, PS KILL, or a fault, then P6 is high. 2 AC Pfail I C port P7. P7 is high except when the power supply turns the main outputs, not +3.3 Vsb, off due to an AC failure (AC missing or too low for power supply operation). If the supply is turned off due to -PS ON, PS KILL, or a fault, then P7 remains high. Fan Fault The PSU will provides an open collector Tach 1 output. Tach 1 This signal is generated from the fan. The signal should generate 2 pulses per revolution. The logic in the system will be operating at 3.3 V. 2 advancedenergy.com
