D1U54-D-450-12-HxxC Series

54mm 1U Front End DC-DC

Power Supply Converter

PRODUCT OVERVIEW

The D1U54-D-450-12-HxxC series power modules are very high efﬁciency, 450 watt DC input front end supplies, with a

12Vdc main output and a standby output. An active (digital) current share characteristic is provided to allow units to

operate in parallel and share load current. The power supply may be hot plugged; recovers from overtemperature faults,

and has status LEDs on the front panel in addition to hardware signal logic and PMBus™ status signals. The low proﬁle

1U package and 14.8W/cubic inch power density make them ideal for delivering reliable, efﬁcient power to networking

equipment, workstations, storage systems and other 12Vdc distributed power architectures.

These models are intended to complement the appropriate D1U54P-W-450-12-HxxC AC input variant.

Load Capacitance

μF

¹Ripple and noise are measured at the output connector, with 0.1 μF of ceramic capacitance and 10 μF of tantalum capacitance on

each of the power supply outputs. A short coaxial cable to the measurement ‘scope input, is used.

²Measurements assume the use of the minimum load capacitance as specified for the main 12Vdc output and a minimum load of 5%.

Below 5% loading the overall voltage deviation shall be within 2.5%.
