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 48V with a standby output of either 5V, 3.3V, or 12V.
Packaged in a 1U low profile chassis, it is designed to deliver reliable bulk power to servers, worksta-
tions, 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 autorecover from overtemperature 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. A short coaxial cable with 50ohm scope termination is used.
