Description
PULS POWER SUPPLY CT5.121
CT-Series-3-PHASE, 12V, 8A, 96W.
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, 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.

OUTPUT:-
The output provides a SELV/PELV rated voltage, which is galvanically isolated from the input voltage.The device is designed to supply any kind of loads, including unlimited capacitive and inductive loads.The output is electronically protected against overload, no-load and short-circuits. In case of a protection event,audible noise may occur.
| Output voltage | Nom. | 12V | |
| Adjustment range | 12-15V | Guaranteed value | |
| Max. | 16V | This is the maximum output voltage which can occur
at the clockwise end position of the potentiometer due to tolerances. It is not a guaranteed value which can be achieved. |
