250W - 500W DC/DC Converters

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 aluminum packages. These enclosures also protect internal electronic boards from condensation and the ingress of oil, salt, sand, insects and other environmental contaminants.
• Custom connections.
