screw-clamp connections

output overvoltage protection (58Vdc typ. / 60Vdc max.)
Short-circuit current -- max. 7A continuous current (short circuit impedance 90mΩ)
Series / parallel operation -- The DC/DC-converter can be paralleled to increase the output power. Devices can be paralleled for 1+1 redundancy to gain higher system availability. Daisy chaining (jumping from 1 DC/DC-converter output to the next) is allowed as long as the average output current through 1 terminal pin does not exceed 25A. If the current is higher use a separate distribution terminal block.
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 CD10.482 is a DIN-rail mountable DC/DC converter of the DIMENSION series which provides a floating stabilized and galvanically separated SELV/PELV output voltage. The CD-Series is part of the DIMENSION power supply family. The most outstanding features of CD10.482 are the high efficiency the small size and the wide operational temperature range. The CD-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. High immunity to transients and power surges as well as low electromagnetic emission and a large international approval package for a variety of applications makes this unit suitable for nearly every situation.
