DIU-W-1600-48-Hx Series AC-DC Front End Power Supply

Category: Electronics, Murata Manufacturing Co Ltd, Other Semiconductors

The DIU-W-1600 Series by Murata Power Solutions is a highly efficient front-end AC-DC power supply, designed primarily for use in hot-swapping redundant systems. With a substantial 1600 Watt output and a power-factor-corrected (PFC) design, it ensures reliable and potent bulk power supply to 48V distributed power architecture systems. Predominantly leveraged in servers, workstations, and storage systems, it has a standout feature of being packaged within a low profile 1U form factor, ideal for high power density environments.

Selection Guide

The selection guide lists different models in the series with several slated for discontinuation. The guide includes the main output specification of 1600W at high line AC and 1200W at low line AC along with the main output voltage of 48V. Each model variant provides either a 3.3V, 5V, or 12V standby output, with specific airflow direction for cooling, either back to front or front to back.
