PULS CT5.121 INTRODUCTION
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 CT5.121 are the high efficiency, electronic inrush current limitation, active input transient filter and wide operational temperature range, small size, and other technological design concepts.
The C-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.
