The Dimension CD5-series offer DIN-rail DC/DC

converters in the 120W output power range in a very

compact housing.

These DC/DC converters are allowed to run from a

battery, can also be used to refresh and stabilize the

24Vdc on the end of a long cable or to isolate

specific loads from the 24V bus voltage.

The CD5.241 includes all the essential basic functions

while the CD5.241-S1 is equipped with quick-connect

spring clamp terminals, a DC-OK-contact which

monitors the output and an input-low-relay-contact.

Both devices have a power reserve of 20% and this

extra power can be used continuously up to +45°C.

TERMINOLOGY AND ABREVIATIONS

PE and symbol PE is the abbreviation for Protective Earth and has the same meaning as the symbol .

Earth, Ground This document uses the term “earth” which is the same as the U.S. term “ground”.

T.b.d. To be defined, value or description will follow later.

DC 24V A figure displayed with the AC or DC before the value represents a nominal voltage with

standard tolerances included.

E.g.: DC 12V describes a 12V battery regardless whether it is full (13.7V) or flat (10V)

24Vac A figure with the unit (Vdc) at the end is a momentary figure without any additional

tolerances included.
