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 -- can be paralleled to increase the output power. The output voltage of all DC/DC converters 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 and DC/DC converters without compromising quality reliability and performance
The C-Series is part of the DIMENSION power supply family
The most outstanding features of CPS20.241-D1 are the wide DCinput range high efficiency electronic inrush current limitation 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-D1 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.
