output overvoltage protection (18Vdc typ. / 20Vdc max.)
active (input inrush current limiter)
Overload / short-circuit current -- max. 15A continuous current
Series / parallel operation -- Power supplies can be paralleled to increase the output power. The output voltage of all power supplies shall be adjusted to the same value (+/-100mV) in Single use mode with the same load conditions on all units
Back-feeding loads max. 25V -- The unit is resistant and does not show malfunctioning when a load feeds back voltage to the power supply. It does not matter whether the power supply is ON or OFF. The absorbing energy can be calculated according to the built-in large sized output capacitor.

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 the 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.
