PRODUCT OVERVIEW

The D1U86G-W-460-12-HxxDC is a bulk front end power supply which meets the needs of systems requiring high

efficiency distributed power architectures. The output power of this supply is rated at 460W with one main and one

standby output. The supply provides high efficiency performance, 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-profile

design and dense packaging makes this supply ideal for delivering reliable, efficient power to servers, workstations,

storage devices and other distributed power systems.
