Compact power supplies

Compact high density rack mounting power supplies from Emerson Network Power are available in ratings of 450, 550, 650 and 850W.

Using a common 1U by 2U housing, the modules are said to provide a solution to the need for space efficient distributed power.

Called the Astec DS series, the modules accept a universal ac input and provide a single 12V dc output ranging from 37 to 70A. A separate supervisory 3.3V/3A output is also available. Power efficiency is claimed as 84%.
