ABSOPULSE Electronics Ltd. 750Vdc Input, 3kW Rugged DC-DC Converter for Railway & Other Heavy-duty Applications HVI 3KR-3U4

Description
Field-proven rugged design For train and mobile applications Cooling by high quality built-in fans Full electronic protection Wide input range (EN50155) Redundancy diode This rugged, railway quality DC-DC converter utilizes field-proven technology to generate the required output power. It is a mature design with a track record in numerous applications. The converter is designed to meet EN50155 for electronic equipment used on railway rolling stock. It accepts an input voltage of 750Vdc (525V-975Vdc range), the traction voltage typically required for mass transit vehicles such as trams, metros and light rail, and mining locomotives. The converter is built with three internal power modules operating parallel via redundancy diodes. This modular construction provides inherent redundancy; the failure of one internal module would cause a 33% drop in output power while the unit remains functional at 2000W. The converter can therefore also be used as a 2000W redundant power supply. The redundancy diodes also allow the connection of several units parallel. High quality built-in fans provide sufficient airflow for operation within the specified temperature range without de-rating. The fan draws air into the unit, which exhausts at the terminal side of the unit. All heat generating components are installed on aluminum heatsink blocks which are thermally connected to the base plate. This also ensures exceptional mechanical ruggedness. Conformal coating provides protection against humidity and airborne contaminants. Full electronic protection, low component count, large design headroom and the exclusive use of components with established reliability contribute to a high MTBF. It is manufactured at our plant under strict quality control. Industrial quality versions of this design are also available.
