D1U4-W-1600-12-Hx Series
AC/DC Front End Power Supply
PRODUCT OVERVIEW
The D1U4-W-1600-12-Hx is a 1600 Watt, power-factor-corrected (PFC) front-end power supply for hot-swapping
redundant systems. The main output is 12V with a standby output of either 5V or 3.3V. Packaged in a 1U low-pro?le
enclosure, it is designed to deliver reliable bulk power to servers, workstations, storage systems or any 12V distrib-
uted power architecture systems requiring high power density. The highly ef?cient electrical and thermal design with
internal cooling fans supports reliable operation conditions. The D1U4-W-1600-12-Hx is designed to autorecover
from overcurrent and overtemperature faults. Status information is provided with front panel LEDs, logic signals and
I 2 C management interface. Four units can be packaged into an optional 19" 1U power shelf to provide up to 6.4kW 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. A short coaxial cable with 50ohm scope termination is used. See Ripple Test Setup
diagram.
