DC/DC Converters

From 0.5 Watts to 30000 Watts to Any DC to DC input/output configuration Helios is able to supply an extensive range of converters designed to meet the needs and criteria of your application. Typical application environments include railway, transportation, heavy industry, industrial automation, power utilities, telecommunications, mining, marine and many others. For OEM solutions we offer a range of Single and Dual in Line Package (SIP/DIP) models, with semi-regulated and fully regulated units to high power PCB mount modules. To complement this we also offer chassis mount, DIN mount and rack mount converters to build our comprehensive range. For rail applications our ruggedized DC/DC converters are designed to meet EN50155.

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.
