ESCRIPTION
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.
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.
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.
