The DS1050 series bulk front end AC-DC power supply accepts a wide range 90–264 Vac input and provides a main 12 V output plus a 3.3 V or 5 V standby output. Rated at 1,050 watts it is an 80 Plus Gold supply with a high half-load efficiency of 92%. Housed in an industry standard 1U x 2U rack-mounting package, the power supply is ideal for space-constrained applications. This series comes in two airflow versions – dc-connector to ac-connector and vice versa.The main 12 V output can deliver up to 87 amps and stays within regulation down to zero load, making it perfect for feeding downstream DC-DC converters in systems that use distributed power architectures (DPA). Standard features include active current sharing, internal ORing FETs and an EEPROM for storing service data to facilitate efficient field replacement. The power supply is hot pluggable and ideal for fault tolerant and N+1 redundant applications. This digitally-controlled power supply is PMBus™ compliant. A built-in I2C serial interface allows set-up, monitoring and control to be performed using Artesyn Embedded Technologies' universal PMBus graphical user interface.Universal PMBus GUI Software Package\n
