Safety of operator accessible output circuit
If the output circuit of a DC-DC converter is operator acces-
sible, it shall be an SELV circuit according to the IEC/EN
60950 related safety standards
The following table shows some possible installation con-
figurations, compliance with which causes the output circuit
of the DC-DC converter to be an SELV circuit according to
IEC/EN 60950 up to a configured output voltage (sum of
nominal voltages if in series or +/– configuration) of 42 V.
However, it is the sole responsibility of the installer to en-
sure the compliance with the relevant and applicable safety
regulations. More information is given in: Technical Infor-
mation: Safety.
1 The front end output voltage should match the specified input voltage range of the DC-DC converter.
2 The earth connection has to be provided by the installer according to the relevant safety standard, e.g. IEC/EN 60950.
3 The installer shall provide an approved fuse (type with the lowest rating suitable for the application) in a non-earthed input conductor
directly at the input of the DC-DC converter (see fig.: Schematic safety concept). For UL’s purpose, the fuse needs to be UL-listed.
See also: Input Fuse.
4 Each suppressor diode should be dimensioned in such a way, that in the case of an insulation fault the diode is able to limit the output
voltage to SELV (<60 V) until the input fuse blows (see fig.22: Schematic safety concept).
