Input Filter and Fuse
An input filter and a fuse are incorporated in all converters as
standard. The filter reduces emitted electrical noise and
prevents oscillations caused by the negative input impedance

characteristic of a switched mode regulator. The input fuse
protects against severe defects.
The maximum permissible additionally superimposed ripple v
of the input voltage (rectifier mode) at a specified input
frequency f
The input fuses are specified in the table 3.
Inrush Current
Depending on the input source and the input impedance, the
inrush current into the converter may reach a very high peak
value during the switch-on sequence. It also determine the
rating of input devices such as switches, relays, fuses, etc. To
protect these input devices by limiting the inrush current, we
recommend the choice of the active inrush current limitation
circuit, option E.
