RWY182

DC/DC Converter Dual Output 200W – Rail Applications

The RWY 182 Series fully encapsulated, dual output, railway quality DC/DC converter uses field-proven topology to generate 200W output power. It employs forward topology on one output and push pull topology on the other.Both outputs are individually regulated and current limited. This is a mature product with a track-record in numerous applications. The unit is entirely potted with a thermally conductive MIL?grade silicon rubber compound to ensure immunity to shock, vibration and humidity. It is conduction-cooled via a base plate to a heat sinking surface. 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 EN50155 for Electronic equipment used on rolling stock. The unit is also suitable for transportation, mining, oil rigs, military and other harsh environments.

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
