DC-DC converter power supplies rugged enough for railway applications introduced by Martek Power

TORRANCE, Calif., 30 Jan. 2011. Martek Power in Torrance, Calif., is introducing the CCR050 series DC-DC converters that are rugged enough for railway applications that accept an input voltage range from 16.8 to 137.5 volts DC and provide up to 50 Watts. Nominal output voltage is 24 volts DC; models with alternative output voltages are available on request. Efficiency levels are better than 85 percent at 72 volts input voltage.

The rugged power supplies are designed to satisfy the majority of rolling stock DC power applications with one unit. The power electronics units comply with the requirements of EN50155 for railway applications, including EN 50121-3-2, EN55011, and EN 61373.

Key features include reverse input voltage protection, over voltage protection, permanent short circuit protection and inrush current limitation. Operating temperature range is -40 to 70 degrees Celsius 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 by 100 by 35.5 millimeters.
