PRODUCT OVERVIEW
C1U-W-1200-48-Tx Series
AC/DC Front End Power Supply
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 48V and standby output of either 5V, 3.3V, or 12V.
Packaged in U low profile, it is designed to deliver reliable bulk power to servers, workstations, storage
systems or any 48V distributed power architecture systems requiring high power density. The highly
efficient electrical and thermal design with internal cooling fans supports reliable operation conditions.
The C1U-W-1200 is designed to auto-recover from over-temperature faults.

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.
