BAP65R

DC/DC Converter Railway Applications

The BAP65R series DC/DC converters are an upgraded product from the very popular and mature BAP industrial grade product, with, field proven reliability over 20 years.These units are specifically designed for rolling stock/rail applications and can be manufactured to customer specifications with total flexibility to match customer requirements.

Units are supplied with conformal coating of PCBs and a high level of ruggedization for shock & vibration to IEC 61373. Designed for a wide range of input voltage options from 24 ~ 168vdc and any output voltage from 12 ~ 130VDC.

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
