DS1100SLPE-3 Series


1100 W Front End AC-DC Power Supplies

The DS1100SLPE series bulk front-end AC-DC power supply accepts a wide range of 90 to 264 VAC input and provides a main 12 V output plus a 3.3 V standby output. Rated at 1100 W it is an 80 Plus Platinum supply with a high peak efficiency of 94%. With an industry-standard 1U x 2.1-inch rack-mounting package housing, 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 A 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 paralleled for high-current applications without additional components.
