Description
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 a 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
