DS1100TDC Series

1100 Watt Front End DC-DC Power Supplies

The DS1100TDC series bulk front end DC-DC power supply accepts a wide range -40 to -72 Vdc input and provides a main 12 V output plus a 3.3 V standby output. Housed in an industry standard 1U x 2.1 inch rack-mounting package and able to deliver 1,100W, the power supply is ideal for space-constrained applications. This series comes in two airflow versions – output-connector to input-connector and vice versa.

The main 12 V output can deliver up to 91.7 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 Power' universal PMBus graphical user interface.
