PRODUCT OVERVIEW
The D1U4-W-1200 is a 1200 Watt, power-factor-corrected (PFC) front-end power supply for hot-
swapping redundant systems. The main output is 12V 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 12V distributed power architecture systems requiring high power density. The highly efficient
electrical and thermal design with internal cooling fans supports reliable operation conditions. The
D1U4-W-1200 is designed to auto-recover from over-current and 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.

1 _{Ripple and noise are measured with 0.1 uF of ceramic capacitance and 2 x 270 uF of OSCON 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. See Ripple Test Setup diagram.
