11. Protection Features
Output over-current protection not included
Reverse input polarity protection included unit does not start when input voltage is reversed
Degree of protection IP 20 EN/IEC 60529
Penetration protection > 3.6mm e.g. screws, small parts
Over-temperature protection not included
Input transient protection not included
Output transient protection included see EMC section
Internal input fuse not included
12. Safety Features
Input / output separation no galvanic separation 200V epitaxial diode between input and output
Safety level of output voltage The output voltage is regarded to be SELV (EN 60950-1) or PELV (EN 60204-1, EN
50178, IEC 60364-4-41) if the input voltage fulfills the requirements for a SELV
source or PELV source.
Class of protection III PE (Protective Earth) or chassis connection not required
PE resistance < 0.1Ohm between housing and chassis-ground terminal
13. Dielectric Strength
The input and output voltages have the same reference, are floating and have no ohmic connection to ground.
Type and factory tests are conducted by the manufacturer. Field tests may be conducted in the field using the
appropriate test equipment which applies the voltage with a slow ramp (2s up and 2s down). Connect input/output
terminals together before conducting the test.
When testing, set the cut-off current settings to the value in the table below.
