D1U54-D-2000-12-HBxC Series
54mm 1U Front End DC-DC Power Supply Converter
PRODUCT OVERVIEW
D1U54-D-2000-12-HBxC is a series of highly efficient Low Voltage DC (LVDC) input front end power supplies featuring a 12Vdc main
output, capable of active current sharing and a standby output. A multifunctional status LED, hardware logic signals and PMBus™
digital communications cold redundant capability are standard features. The low profile 1U, 46.9W/cubic inch package make this
series ideal for delivering reliable, efficient power to servers, workstations, storage systems and other 12V distributed power
architectures.
