The Dimension C-Series are cost optimized power

supplies without compromising quality, reliability and

performance. The C-Series is part of the DIMENSION

power supply family. The most outstanding features of

CT10.481 are the high efficiency, electronic inrush

current limitation, active input transient filter and wide

operational temperature range.

The C-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. Additionally, the CT10.481 can deliver 3

times the nominal output current for 10ms which helps

to trip fuses on faulty output branches.
