Leakage Currents in AC-DC operation
Leakage currents flow due to internal leakage capacitance
and RFI suppression Y-capacitors. The current values are
proportional to the mains voltage and nearly proportional to
the mains frequency and are specified at an input voltage of
264 V (50 Hz) where phase, neutral and protective earth
are correctly connected as required for class I equipment.
Under test conditions the leakage current flows through a
measuring instrument (MI) as described in fig.:
Measuring
instrument for earth leakage current tests, which takes into
account impedance and sensitivity of a person touching
unearthed accessible parts. The current value is calculated
by dividing the measured voltage by 500
. If inputs and/or
outputs of K-units are connected in parallel, their individual
leakage currents are added.

Safety of operator accessible output circuit
If the output circuit of an AC-DC converter is operator ac-
cessible, it shall be an SELV circuit according to the IEC/EN
60950 related safety standards.
The following table shows a possible installation configura-
tion, compliance with which causes the output circuit of an
K series AC-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 36 V.
However, it is the sole responsibility of the installer to as-
sure the compliance with the relevant and applicable safety
regulations. More information is given in
Technical Informa-
tion: Safety.
If the K series AC-DC converters are used as DC-DC con-
verters, please refer to the data sheet
