Description
DCW102R
DC/DC Converter Dual Output – Railway Applications
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.
Rugged Mechanical Designs
Helios power supplies are ruggedly constructed and can be customized for specific mechanical requirements. Standard mechanical packages and ruggedization options include:
- Chassis and wall-mountable units in vented conduction/convection or fan-cooled enclosures
- DIN-rail and open-frame format available for many designs
- Plug-in (Eurocard) format for modular power systems in 19 inch or 23-inch racks
- Conformal coating and ruggedizing are standard
- Full encapsulation (potting) in a thermally conductive MIL-grade silicon rubber compound with UL94V-0 flammability rating for immunity to high levels of shock and vibration, humidity, moisture, dust, salt, oil, insects and other contaminants
- Enclosure in rugged, IP66- or IP67-rated waterproof, dustproof and explosion-proof die-cast aluminium packages. These enclosures also protect internal electronic boards from condensation and the ingress of oil, salt, sand, insects and other environmental contaminants
- Custom connections
- Portable DC Power Supplies
