PRODUCT OVERVIEW
D1U-W-1200-12-Hx Series
AC-DC Front End Power Supply
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 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 D1U-W-1200 is designed to auto-recover from over-temperature faults.
Status information is provided with front panel LEDs, logic signals and I
2
C management interface. Three units can be
packaged into a 19" 1U power shelf to provide up to 3.6kW of power.

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.
