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
signals and I
2
C management interface. Three units can be packaged into an optional 19" 1U power shelf
to provide up to 8.4kW of power.

Ripple and noise are measured with 0.1 uF of ceramic capacitance and 10 uF of tantalum capacitance on each of
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.
