1 Source impedance according to prETS 300132-2 (Ver. 4.3).
2 The switching frequency varies with input voltage and output load (see: Typical performance curves).
Reverse Polarity Protection at Input
The suppressor diode at the input also provides for reverse
polarity protection by conducting current in the reverse di-
rection, thus protecting the unit. An external fuse is required
to limit reverse current:
– for BG units a fast 3 A (F3A) fuse is required.
– for CG units a fast 1.25 A (F1.25A) fuse is required.
Filter recommendations for compliance with
EN 55022, level B
Electromagnetic
emission
requirements
according
to
EN 55022, level B can be achieved by adding an external
filter to the input of the converter. (tbd)
Input Transient Voltage Protection
A suppressor diode at the input together with the input filter
provides an effective protection against input transients
which may be caused for example by short circuits accross
the input lines where the network inductance may generate
high energy pulses.

1 To achieve higher input transient ratings an additional inductor
and capacitor should be provided externally.
Inrush current
The inrush current has been kept as low as possible by
choosing a small internal input capacitance.
