output overvoltage protection (58.5Vdc typ. / 60Vdc max.)
Overload / short-circuit current -- 7A average (R.M.S.) current / min. 40A (typ. 50A) up to 15ms at load impedance <10mΩ
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 C-Series is part of the DIMENSION power supply family
The most outstanding features of CPS20.241 are the high efficiency electronic inrush current limitation active PFC wide operational temperature range.
The small size is achieved by a synchronous rectification and further technological design details.
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 CPS20.241 can deliver about 4 times the nominal output current for 15ms which helps to trip fuses on faulty output branches.
High immunity to transients and power surges as well as low electromagnetic emission; a DC-OK relay contact and a large international approval package for a variety of applications makes this unit suitable for nearly every situation.
