Inrush current
The inrush current has been kept as low as possible by
choosing a very small input capacitance. A series resistor
may be installed in the input line to further reduce this cur-
rent.

Input Transient Voltage Protection
A built-in suppressor diode provides effective protection
against input transients which may be caused for example
by short-circuits accross the input lines where the network
inductance may cause high energy pulses.

For very high energy transients as for example to achieve
IEC/EN 61000-4-5 or ETR 283 (19 Pfl1) compliance (as per
table:
Electromagnetic Immunity) an external inductor and
capacitor are required. The components should have simi-
lar characteristics as listed in table:
Components for exter-
nal circuitry for IEC/EN 61000-4-5, level 2 or ETR 283
(19Pfl1) compliance.
Note: The suppressor diode D is only necessary for
20 IMX 35 types.

Example for external circuitry to comply with IEC/EN
61000-4-5 or ETR 283 (19Pfl1); the suppressor diode D is
only necessary for 20 IMX 35 types.
Reverse Polarity Protection
The built-in suppressor diode also provides for reverse po-
larity protection at the input by conducting current in the re-
verse direction. An external fuse is required to limit this cur-
rent.
