output overvoltage protection (5.9Vdc typ. / 6.1Vdc max.)
Output protection -- electronically protected against overload / no-load / short-circuits
Short-circuit current -- min. 12A continuous current (short circuit impedance 10mΩ) / max. 20A continuous current (short circuit impedance 10mΩ)
Over-temperature protection -- output shutdown with automatic restart
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. 5.6V -- 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 CD-Series offer DIN-rail DC/DC converters in the 50-120W output power range in a very compact housing.
These DC/DC converters can also to run on a battery or similar sources.
The CD5.051 converts 24Vdc on the input to 5Vdc at the output.
The device includes all the essential basic functions and has a power reserve of 20% included.
This extra power can be used continuously up to +45°C.
The output is electrically isolated from the input in a safe way.
The input is protected against reversed voltages and contains a soft start function.
