C&D Technologies Packs 1600W plus Higher Efficiency and Functionality Into An Ultra-Compact 1U Package

C&D’s D1U Series of 1U High, Redundant, Hot-Plug, Front-end Power Supplies deliver 900W-1600W with 90.6% Efficiency at 17.5W/cu inch Power Density for 12V or 48V Distributed Power Architecture Applications

The D1U series of power factor-corrected (PFC) front-end power supplies support N+1 redundant hot swapping systems ranging from 900W to 1600W of output power. The main output is 12V or 48V and standby output of either 3.3V or 5V, or 12V for 48V output model. Packaged in 1U low profile, it is designed to deliver reliable bulk power to servers, workstations, storage sys Front-end Power Supplies tems or any 12V or 48V distributed power architecture systems requiring high efficiency and high power density. The highly efficient electrical and thermal design with internal cooling fans supports reliable operation conditions. The D1U series is designed to auto-recover from over-current and over-temperature faults. Status information is provided with front panel LEDs, logic signals and I²C management interface. Three units can be packaged into an optional 19” 1U power shelf to provide up to 4.8kW of power.
