DS1100SLPE-3 Series 1100 Watt Front End AC-DC Power Supplies


The DS1100SLPE 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 standby output. Rated at 1,100 watts it is an 80 Plus Platinum supply with a high peak efficiency of 94%. Housed in an industry standard 1U x 2.1 inch 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 90 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). Active current sharing enables multiple supplies to be paralleled for very high current applications without need of additional components. The power supply is hot pluggable and ideal for fault tolerant, N+1 and N+N 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.
