375, 500 Watt AC-DC and DC-DC DIN-Rail Converters
Leakage Currents
Leakage currents flow due to internal leakage capacitance
(mainly the Y-capacitors). The current values are proportional
to the voltage V i and the frequency f i of the supply (mains). The
leakage currents are specified at maximum operating input
voltage, provided that phase, neutral, and protective earth are
correctly connected as required for class I equipment.
Caution: Leakage current may exceed 3.5 mA, if f i > 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 the safety standards IEC/EN
60950.
Description of Options
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.
LED Indicator
A green LED is activated, when the output voltage V o 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.
Table 15: Pin allocation of the 9 pin D-SUB connector
Single options D1, D2, D5, R are available on the AUX1
terminal (10), referenced to Vo – or Vo2–.
Option M1 and M2 designate a combination of several options
accessible via a D-SUB connector or in some cases on the
AUX1 and AUX2 terminals. Option M1 includes the function SD.
Note: In double-output models, the options D1, D5, R, and SD
concern only output 2 connected to terminals 6, 7, 8, and 9.
