The DCW102R series DC/DC converters are designed for use on Rail Rolling Stock and for many extremely harsh environments.V1 is regulated, with the second output tracking.
This rugged, industrial quality DC/DC converter uses a field-proven topology to generate up to 100W 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.
Helios power supplies are ruggedly constructed and can be customized for specific mechanical requirements. Standard mechanical packages and ruggedization options include:
|Model||Input Options ( V)||Standard Outputs( V, A)||Power
|DCW102R||24V, 36V, 48V
|V1: 12V 2A
V2: 12V 2A
|These DCW102R is manufactured to order with customer specifying the
input / output voltage combinations.
