Product Description
The DIMENSION C-series are cost-optimised 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 the 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 10 ms which helps to trip fuses on faulty output branches.
