86mm 1U Front End AC-DC Power Supply Converter
PRODUCT OVERVIEW
The D1U86G-W-460-12-HxxDC is a bulk front end power supply which meets the needs of systems requiring high
ef ciency distributed power architectures. The output power of this supply is rated at 460W with one main and one
standby output. The supply provides 80 PLUS gold ef ciency, hot plug capability, and parallel operation with droop
current sharing. Closed-loop internal fan cooling provides reliable long life operation. Industry standard PMBus
communication protocol makes system integration with this supply seamless and straightforward. The low-pro le
design and dense packaging makes this supply ideal for delivering reliable, ef cient power to servers, workstations,
storage devices and other distributed power systems.
