DS1100SDC Series 12V 1100 Watt Power Supplies (48 V DC Input)


The DS1100SDC-3 series bulk front end DC-DC power supply accepts a wide range -36 to –72 VDC input and provides a main 12 V output plus a 12 V standby output. It is rated at 1,100 watts. Housed in a 1U high rack-mounting enclosure with a short form factor that frees up system space, the DS1100SDC-3 has a very high power density of 24 watts per cubic inch. This series comes in two airflow versions – dc-connector to ac-connector and vice versa. The series is also in the same form factor and has the same output configuration as the DS1100PED-3.

The main 12 V output can deliver up to 91.76 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 DS1100SDC-3 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.
