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.
