The CD10.241 is a DIN-rail mountable DC/DC converter of the DIMENSION series which provides a floating stabilized and galvanically separated SELV/PELV output voltage. The CD-Series is part of the DIMENSION power supply family. The most outstanding features of CD10.241 are the high efficiency the small size and the wide operational temperature range. The CD-Series includes all the essential basic functions. The devices have a power reserve of 20% included which may even be used continuously at temperatures up to +45°C. High immunity to transients and power surges as well as low electromagnetic emission and a large international approval package for a variety of applications makes this unit suitable for nearly every situation.
