D1U54-D-1500-12-HxxC Series
54mm 1U Front End DC-DC Power Converter
PRODUCT OVERVIEW
D1U54-D-1200-12-HxxC series are highly efficient 1500 watt, DC input front end power modules with a 12V main
output and a choice of 3.3V, 5V or 12VDC (30W max) standby rail.The power module is able to current share with up to
eight (8) other power modules of the same type operating in parallel or N+1 redundancy. The supplies may be hot
plugged, and include integral output isolation devices.
The power modules are fully protected from overload and overvoltage and are able to auto-recover from
overtemperature faults. A Status LED is provided on the front panel and additional control and status reporting is
provided by hardware logic signals and via a PMBus™ digital interface.
A low profile sub 1U height enclosure with power density of >35W/in3 make this an excellent choice for delivering
reliable, efficient power to servers, workstations, storage systems and other 12V distributed power systems
including direct operation from intermediate bus converters.

Load Capacitance
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 Minimum load 5A
3 Minimum load 0.25A
