W Series Data Sheet
125, 250 Watt AC-DC and DC-DC DIN-Rail Converters
Isolation
The electric strength test is performed in the factory as routine
test in accordance with EN 50116 and IEC/EN 60950 and
should not be repeated in the field. Power-One will not honor
any warranty claims resulting from electric strength field tests.
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. They are specified at maximum operating
input voltage where phase, neutral, and protective earth are
correctly connected as required for class I equipment.
Leakage current may exceed 3.5 mA, if fi > 63 Hz.
Safety of Operator-Accessible Output Circuits
If the output circuit of a converter is operator accessible, it shall
be a SELV circuit according to IEC/EN 60950 related safety
standards.
The converters have SELV output circuits up to an output
voltage of 57.5 V. However, if the isolated outputs are
connected to another voltage source or connected in series
with a total of >57.5 V the outputs are hazardous.
It is the sole responsibility of the installer to ensure the
compliance
with
the
relevant
and
applicable
safety
regulations.
LED Indicator
A green LED is activated, when the output voltage Vo is within
the normal operating tolerance band.
Note: This LED is also activated, when the converter is not
powered by the input, but a loaded battery is connected to the
output.
