1000 Watt, DO-160
Aircraft Power Supply

Product Description

This is a single output, 1000 watt, DO-160 grade, power supply designed to comply with Boeings aeronautics specification requirements for category (WF) equipment.  This unit was designed for an unique aircraft application that required a smaller size footprint and could be mounted inside a sealed enclosure directly to a coldplate or heatsink. This product is design to comply with Boeings DO-160 EMC Section 16 & 17.
