active (input inrush current limiter)
Overload / short-circuit current -- max. 11.5A 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. 63V -- 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 CT10.481 are the high efficiency electronic inrush current limitation active input transient filter and wide operational temperature range. The C-Series includes all the essential basic functions The devices have a power reserve of 20% included 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.
