The D1U5CS-H-2825 is a 2825 Watt, power-factor-corrected (PFC) front-end power supply for redundant systems. The
main output is 12V and the standby output is 5V. Packaged in 1U low profile, it is designed to deliver reliable bulk power
to servers, workstations, storage systems or any 12V distributed power architecture system requiring high power density.
The highly efficient electrical and thermal design with internal cooling fans supports reliable operating conditions. The
D1U5CS-H-2825 is designed to autorecover from over-temperature faults. Status information is provided with front panel
LEDs, logic signals and I
2
C management interface.
