The DCW152R series DC/DC converters are designed for use on Rail Rolling Stock and for many extremely harsh environments.
This rugged, industrial quality DC/DC converter uses a field-proven topology to generate up to 150W continuous power, depending on the input/output configuration (i.e. efficiency).It is a mature design with a track record in hundreds of applications.
The series has large design headrooms and it is rated for operation over a -25 to +70oC temperature range. It is cooled by conduction via baseplate to a heatsinking surface and by natural convection.These models are fully ruggedized and conformal coated for immunity to shock, vibration, humidity, moisture, dust and insects.
This chassis-mount design is optimized for low component count and high efficiency. The use of components with established reliability results in a high demonstrated MTBF.Customized versions are also available.
