is a 1200 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-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 an optional 19" 1U power shelf to provide up to 3.6kW of power.
The S1U-3X
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 I
2
C 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.

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.
