PRODUCT OVERVIEW
The D1U-W-1200 is a 1200 Watt, power-factor-corrected (PFC) front-end power supply for hot-swapping redundant
systems. The main output is 48V and standby output of either 5V or 3.3V. Packaged in 1U low profile, it is designed
to deliver reliable bulk power to servers, workstations, storage systems or any 48V distributed power architecture
systems requiring high power density. The highly efficient electrical and thermal design with internal cooling fans
supports reliable operation conditions. The D1U-W-1200 is designed to auto-recover from over-temperature faults.
Status information is provided with front panel LEDs, logic signals and I²C management interface. Three units can be
packaged into an optional 19” 1U power shelf to provide up to 3.6kW of power.
The S1U-X3 is a 1U x 19” EIA Rack Mount Power Shelf designed for holding three D1U Front End Power Supplies
in current sharing applications. It is intended for distributed power architecture applications in the Servers, Storage
Networking and Data Communications markets. There are two lug terminal connections for #2 AWG cabling for the DC
output. System connection through the I²C bus reports the performance status of the power supplies within the power
shelf. Two Power Shelves can operate in parallel by an optional Shelf-to-Shelf cable, doubling the power output to the
maximum capability of 7.2kW for two 48V power shelves.
