CD5.241-L1 Datasheet, PDF (20/21 Pages) PULS GmbH – DC/DC Converter

CD-Series
CD5.241-L1
DC/DC Converter 24V, 3.8A
21.8. SERIES OPERATION
This DC/DC-converter is designed to meet the NEC Class 2 requirements. Do not use in series to increase the output
voltage. This would increase the output power for the NEC Class 2 circuit and violates the NEC Class 2 limitations. Use
CD5.241 or CD5.241-S1.
21.9. CHARGING OF BATTERIES
This DC/DC converter can not be used to charge batteries. The output voltage is not adjustable.
21.10.USE IN A TIGHTLY SEALED ENCLOSURE
When the DC/DC converter is installed in a tightly sealed enclosure, the temperature inside the enclosure will be
higher than outside. In such situations, the inside temperature defines the ambient temperature for the DC/DC
converter.
The following measurement results can be used as a reference to estimate the temperature rise inside the enclosure.
The DC/DC converter is placed in the middle of the box, no other heat producing items are inside the box
