D1U54P-W-650-12-HBxC Series
54mm 1U Front End AC-DC Power Supply Converter
PRODUCT OVERVIEW
The D1U54P-W-650-12-HBxC series are very high efficiency 650 watt power factor corrected front end supplies with a
12V main output and a 12V Standby. An active (analogue) current share characteristic is provided to allow units to
operate in parallel. 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
21.4W/cubic inch power density make them ideal for delivering reliable, efficient power to networking equipment,
workstations, storage systems and other 12V distributed power architectures.

1 _{Ripple and noise are measured 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.
2 _{Measurements assume the use of the minimum load capacitance as specified for the main 12V output and a}
minimum load of 5%.
Below 5% loading the overall voltage deviation shall be within ±500mV due to zero load “skip” cycle mode of
operation.
