ESCRIPTION
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.
