The best DCW 150-12FT-P6611

DCW 150-12FT-P6611

This rugged, industrial quality DC/DC converter uses field proven topology to generate 150W output power.  It is a mature design with a track record in hundreds of applications.  This chassis-mount design is also optimized for cost efficiency.  Cooling is via baseplate to a heat-sinking surface and by natural convection.  Additional ruggedizing and conformal coating are available for applications that require higher immunity to shock, vibration and humidity. Low component count, large design headrooms, and the use of components with established reliability result in a high MTBF.  The DCW 150 is manufactured at our plant under strict quality control.
