Railway and Transportation Power Supplies

Polytron Devices, which is our power-supply division at Daburn Electronics & Cable, is a top source for DC-DC power supplies for the rail and transportation sectors. Unlike many of the DC-DC converters our competitors offer, these robust railway power supplies are fully compliant with strict transportation industry standards.

Our inventory of railway power supplies includes 12-, 24- and 110-volt Input DC-DC converters. These products are highly reliable choices for use with transportation and railway machinery and equipment, which provide unique challenges.

A wealth of technical advantages

These DC-DC converters for rail and transportation come in 12 different series, ranging in power from 8 to 200 watts. Single and Dual Output Voltages are available, as well as a variety of package sizes and options including quarter- and half-brick converters and miniature 1″ by 1″ by 0.39″ package compact converters, all with ultra-wide input voltage range.

Polytron’s line of transportation and railway power supplies has many important, unique technical advantages. In addition to meeting the EN50155, EN500121-3, and EN61373 standards of the European Committee for Standardization, these converters have passed all shock and vibration tests. With six-sided continuous shields and reverse polarity protection, they can maintain output voltage for as long as ten milliseconds during power outages. All of the wattages (8-200W) are available with input voltage range choices of 110 (40-160), 24 (9-36), and 48 (18-75) VDC input, and optional wall-mount designs are available.

Our transportation and railway power supplies are highly recommended for many applications in this industry, including the following:

  • Air-conditioner control systems;
  • Broadcasting systems;
  • Computer powering;
  • Fire-alarm systems;
  • LCD display boards for passenger information systems;
  • Lighting, both internal and external;
  • Personal monitors for trains;
  • Test equipment for automobile manufacturing;
  • Ticket machines; and
  • Tracking and communication systems.

In addition to these converters, Polytron offers power supplies for the medical and military sectors, as well as numerous other DC-DC converter types, AC-DC switching power modules, and linear encapsulated power modules.

For nearly half a century, Polytron Devices has been a leading designer of power supplies for many industries. To learn more about these products as well as many additional options, visit Polytron’s website.
