PRODUCT OVERVIEW

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

to provide up to 8.4kW of power.

the power supply outputs. The output noise requirements apply over a 0 Hz to 20 MHz bandwidth. A short coaxial

cable with 50ohm scope termination is used.
