The CCR050 series dc/dc converter target railway applications and satisfy the majority of rolling-stock dc power applications with a single unit. The converters accept a very wide nominal input voltage range from 24 to 110 Vdc (16.8 to 137.5 Vdc full range) and provide up to 50 W output. The nominal output voltage is 24 Vdc with alternative output voltages available. Efficiency levels are >85% at 72-V input voltage.
The dc/dc converters comply with the EN50155 requirements for railway applications, including EN 50121-3-2, EN55011 and EN 61373. The converters feature reverse input voltage protection, overvoltage protection, permanent short-circuit protection and inrush current limitation. Operating temperature range is –40º to 70ºC without derating. They are available in open frame or housed in a metal enclosure. The open-frame version measures 105 x 100 x 35.5 mm.
