Tue, 02/08/2011 - 6:23am
DCDC converter for railwayMartek Power introduced a DC/DC converter designed to satisfy the majority of rolling stock DC power applications with a single unit. As a result, users are able to specify the same power supply no matter what the input voltage demanded by the application, according to the company. The CCR050 Series DC/DC converters accept a very wide nominal input voltage range from 24 V to 110 VDC (16.8 V to 137.5 VDC) and provide up to 50 W. Nominal output voltage is 24 VDC; models with alternative output voltages are available on request. Efficiency levels are better than 85 percent at 72 V input voltage. They comply fully with the requirements of EN50155 for railway applications, including EN 50121-3-2, EN55011 and EN 61373. Features include reverse input voltage protection, over voltage protection, permanent short circuit protection and inrush current limitation. The operating temperature range is -40º to +70ºC without derating. CCR050 Series converters feature faston terminals for both input and output connections and are available open frame or housed in a simple metal enclosure. The open frame version measures 105 mm x 100 mm x 35.5 mm.
