Input Filter and Fuse
An input filter and a fuse are incorporated in all modules as
standard. The filter reduces emitted electrical noise and
prevents oscillations caused by the negative input imped-
ance characteristic of a switched mode regulator. The input
fuse protects against severe defects.
The maximum permissible additionally superimposed rip-
ple
vi of the input voltage (rectifier mode) at a specified in-
put frequency
fi has the following values:
vi max = 10 Vpp at 100 Hz, or Vpp = 1000 Hz/fi 1 V
Inrush Current
Depending on the input source and the input impedance,
the inrush current into the regulator may peak several thou-
sand amperes during the switch-on sequence. It also deter-
mine the rating of input devices such as switches, relays,
fuses etc. To protect these input devices by limiting the peak
of the inrush current we recommend the use of the active
inrush current limitation circuit, option E.
