URED20W

DC/DC Converter Single & Dual Output: 20W

Converter designed to meet the Railway standards EN50155 and EN45545-2. Mounting is available in both Chassis and DIN Rail Mounting. 4:1 Input voltage: 9-36, 18-75, 43-160 VDC.  Output Voltage: 3.3, 5, 12, 15, ±12, ±15 VDC.

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
