PRODUCT OVERVIEW
D1U54S-D-1200-12-HxxC series of 1200W highly efficient, DC-DC front-end power supply converters provide
a 12Vdc main output. These power modules adopt an active current-sharing feature for parallel or redundant
operation and are fully protected from over-voltage, over-current, and over-temperature faults, and also
includes a standby output.
LED status indicators and corresponding hardware logic signals are provided in addition to a comprehensive
PMBus™1.2 compliant digital communication bus. These features provide status monitoring, configuration,
and control capability.
The slim, compact 1U package achieves >39W/in3 and is ideal for delivering robust power to servers,
workstations, storage, network systems, or other applications requiring 12V distributed power architecture.
