D1U-W-2000-48-Hx Series
www.murata-ps.com
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 redundant 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 architecture 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.

Ripple and noise are measured with 0.1 uF of ceramic capacitance and 10 uF of tantalum capacitance on each of
the power supply outputs. The output noise requirements apply over a 0 Hz to 20 MHz bandwidth. A short coaxial
cable with 50ohm scope termination is used.
