PRODUCT DESCRIPTION The Dimension CT-Series are cost optimized power supplies without compromising quality, reliability and performance. The CT-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 CT-Series includes all the essential basic functions. The devices also offer PowerBoost: Power reserves of 20%, 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.
