PRODUCT OVERVIEW

The D1U86-D-1600-12-HBxDC series are highly efficient 1600 watt, DC input front end supplies with a

12V main output and a 12V (30W) standby. They have current sharing and up to 8 supplies may be

operated in parallel. The supplies may be hot plugged, they recover from overtemperature faults, and

have logic and PMBus monitoring and control. Their low profile 1U package and >38.6W/cubic inch

power density make them ideal for delivering reliable, efficient power to servers, workstations, storage

systems and other 12V distributed power systems.
