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 CT5.121 are the high efficiency, electronic inrush current limitation, active input transient filter and wide operational temperature range, the small size and other technological design concepts. The CT-Series includes all the essential basic functions. The CT5.121 utilizes only 2 legs of a 3-phase system which saves wiring and installation costs. Furthermore, this allows a smaller unit without compromising the size of the terminals. Due to the low power consumption, an unbalancing of the individual phases is not expected.
