Now available for industrial control and embedded rack systems applications is the DRL Series from Astrodyne (www.astrodyne.com). Featuring a cage-covered package with snap-on DIN rail mounts, the DRL Series of enclosed switching power supplies is intended for use in size-restrictive applications that require power levels of 25-320W output. The series accepts universal input from 85 to 265V ac, and 30 models are available to provide single outputs from 5 to 48V dc. It also comes with integral input EMI filtering and 3,000V ac I/O isolation.
