CD5.121

CD-Series

DC/DC Converter 12V, 8A

Output protection

Output over-voltage protection

typ. 16.5Vdc

max. 16.8Vdc

in case of an internal power supply defect, a redundant

circuit limits the maximum output voltage. The output

shuts down and automatically attempts to restart.

Reverse input polarity protection Included

unit does not start when input voltage is reversed

Output over-current protection

see Fig. 5-1

Degree of protection

IP 20

EN/IEC 60529

Penetration protection

> 3.5mm

e.g. screws, small parts

Over-temperature protection

yes

output shut-down with automatic restart

Input transient protection

MOV

Metal Oxide Varistor

Internal input fuse

included

not user replaceable

In case of a protection event, audible noise may occur.

Classification of output voltage

SELV

IEC/EN 60950-1

PELV

IEC/EN 60204-1, EN 50178, IEC 62477-1, IEC 60364-4-41

Class of protection

III

PE (Protective Earth) connection not required. A

connection of the “Chassis Ground” pin to earth is

recommended for best EMI performance

Isolation resistance

> 5MOhm

input to output, 500Vdc

PE resistance

< 0.1Ohm

between housing and Chassis Ground terminal

Touch current (leakage current)

The leakage current which is produced by the DC/DC converter itself depends on the

input voltage ripple and need to be investigated in the final application.

For a smooth DC input voltage, the produced leakage current is less than 100μA.
