The Dimension CD-Series offer DIN-rail DC/DC converters

in the 92-120W output power range in a very compact

housing. These DC/DC converters are allowed to run

with a battery or similar sources.

The CD5.121 converts a 24V voltage to a 12V voltage.

The CD5.121 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.
