C1U-W-1200-12-Tx Series
AC/DC Front End Power Supply
PRODUCT OVERVIEW
The C1U-W-1200 is a 1200 Watt universal AC input, power-factor-corrected (PFC) front-end power supply for general
applications. The main output is 12V and standby output of either 5V or 3.3V. Packaged in U low proï¬le, 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 efï¬cient electrical and thermal design with internal cooling fans sup-
ports reliable operation conditions. The C1U-W-1200 is designed to auto-recover from over-temperature faults.

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.
