Our railway converters power on-board and track-side electronic systems in railway projects around the world. They are installed in mass transit vehicles such as trams, metros and light rail, mining locomotives and in an extensive range of trackside equipment. Helios’ railway power supplies are designed to meet all required rail-specific standards. If you require a standard not on our list below, please contact us.
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.
