PRODUCT OVERVIEW

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 I2C 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 I2C 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 12V power shelves.

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.
