D1U-W-2000-48-Hx Series
AC/DC Front End Power Supply
PRODUCT OVERVIEW
The D1U-W-2000 is a 2000 Watt, power-factor-corrected (PFC) front-end power supply for hot-swapping redun-
dant systems. The main output is 48V and standby output of either 12V, 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 archi-
tecture systems requiring high power density. The highly efficient electrical and thermal design with internal cooling
fans supports reliable operation conditions. The D1U-W-2000 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 a 19" 1U power shelf to provide up to 6.0kW of power.
