Description
DCW100R
DC/DC Converter Railway Applications
The DCW 100R Series rugged, railway quality DC/DC converter uses field-proven topology to generate the required output power.It is a mature design with a track record in numerous applications. Cooling is via base plate to a heat-sinking surface and by natural convection. Ruggedizing and conformal coating provide added immunity to shock, vibration and humidity.
Full electronic protection, low component count, large design headroom, and the use of components with established reliability result in a high MTBF. The unit meets the requirements of EN 50155 for electronic equipment used on railway rolling stock.
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
