LOS, LOR, LOK4000 Series Data Sheet
DIN-Rail Mountable AC-DC (DC-DC) Converters
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
accessible parts. The current value is calculated by dividing
the measured voltage by 500 W. If inputs and/or outputs of
LOS, LOR, or LOK models are connected in parallel, their
individual leakage currents are added.
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.
