The Dimension CD5-Series offers a range of DIN-rail
mountable DC/DC-converters in a very compact
housing.
The CD5.121 converts a 24V voltage to a 12V
voltage. With this DC/DC converter a 12V load can be
supplied in a 24V control environment. The input
source can be a battery, a solar panel or any other
24V sources.
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 funtion.
