450–550 Watt Front End AC-DC Power Supplies


The DS450 and DS550 series bulk front end AC-DC power supplies accept a wide range 90–264 Vac input and provide a main 12 Vdc output, plus a 3.3 Vdc standby output. Rated at 450 watts and 550 watts respectively, the DS450 and DS550 have a typical full load conversion efficiency of 84%. Standard features include active current sharing, internal ORing FETs and an EEPROM for storing service data to facilitate efficient field replacement. An I2C communication interface is provided for the FRU EEPROM data.
