Series Headline 140mm Front End AC-DC Power Supply
Series Description The D1U-H-2800 is a 2800 Watt, power-factor-corrected (PFC) front-end power supply for hot-swapping redundant systems. The main output is -52V and standby output of 12V. Packaged in 1U low profile, it is designed to deliver reliable bulk power to telecom systems or any -52V distributed power architecture systems requiring high power density. The highly efficient electrical and thermal design with internal cooling fans supports reliable operation conditions. The D1U-H-2800 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 8.4kW of power.
