Whether it be a tram, the subway of one of the world's largest cities, or a high-speed train, numerous partners rely on the quality of BLOCK railway products. Auxiliary converters supply the air-conditioning system, lighting, kitchens, or plug sockets of the rail carriage. Transformers provide safe galvanic isolation. Filters and reactors are used for a clean signal between the carriage power supply and the load. DC/DC converters and electronic circuit breakers are found in numerous areas of central supply systems, air-conditioning technology, train communications, in infotainment, and in signal tower technology. Our products are specially developed and designed for railway applications. It goes without saying they comply with all important standards and are tested in the toughest of conditions.

OPERATING UNDER SPECIAL CONDITIONS

Icons für Nässe, Schnee und Staub für die Bahntechnik

Our products for railway technology are tested to a wide variety of humidity, wetness and climate tests. Irrespective of whether the devices were in a water bath for 10 minutes or 24 hours, or are exposed to 100% humidity, they reliably pass our high-voltage and insulation resistance test. Once all tests have been performed exhaustively in the BLOCK test laboratory, resistance to water, snow, and dust is ensured.

Thermometer = Icon für Hitze

Heat presents materials with special challenges. Heavy temperature fluctuations can not only damage insulation. A well-dimensioned cooling system coupled with a correct thermal design ensure that BLOCK products are ideally suited to the demanding requirements for service life in trains.

Icon für Vibration in der Bahntechnik

Strong vibrations occur when changing tracks and at high speeds. They exacerbate wear and have an influence on the connections and windings of the installed components. BLOCK inductors are especially robust with respect to the mechanical stresses of railway applications.
